AB  - In the reaction of acetone solutions of CoX2∙nH2O (X = Cl, Br) with methyl pyruvate semi/thiosemicarbazone (Hmps, Hmpt) the first Co(II) complexes with these ligands, i.e., [Co(Hmps)(H2O)X2] (X = Cl (1), Br (2)), [Co(Hmpt)2][CoCl4]∙2H2О (3) and [Co(Hmpt)2]Br2∙Me2CO (4) were obtained. Complexes 1 and 2 represent the first examples of metal complexes of Hmps. All the obtained compounds were characterized by elemental analysis, conductometry, magnetic measurements, and IR spectra, and for complexes 2–4, single crystal X-ray diffraction analysis was also performed. The effective magnetic moments were close to the upper limit (5 μB) for complexes 1 and 2, and close to the lower limit (4.4 μB) for complexes 3 and 4, and as such are characteristic for high-spin Co(II) complexes. Structural analysis showed that both ligands coordinate in a neutral form in a tridentate manner, via the ester oxygen, imine nitrogen and the oxygen atom of the ureido (Hmps), or the sulfur atom of the thioureido group (Hmpt). The central metal atoms are situated in a deformed octahedral coordination environment. Complex 2 has cis-Br configuration, while complexes 3 and 4 have mer-configuration.

AB  - In the present study we have analyzed effects of Ag+ ions doping on energetic profiles of nanophosphors materials based on fluorapatite crystal system. The UV radiation absorption and luminescence properties of monophase fluorapatite (FAP) and Ag+ doped fluorapatite (AgFAP) nanomaterials obtained by neutralization method were investigated using the photoluminescence spectrophotometry. The excitation-emission profiles of nanomaterials were analyzed statistically by MCR-ALS method and number of fluorophores was extracted. FAP lattice absorbed light at 350 nm in the UVA part of spectrum, and with increasing concentration of Ag+ ions new absorption maximum appeared at 270 nm in the UVC part. Fluorescence of FAP nanoparticles was in violet region of visible part of the spectrum, with a red shift to the green region when Ag+ was doped in lattice. MCR-ALS analyses of fluorescence spectra confirm formation of two maxima, at 484 and 505 nm, as a consequence of Ag+ ions doping in FAP lattice at Ca1 (4f) sites. The results of quantum chemical calculations showed that an Ag+ ion is stronger bonded to the binding site 1 (-1352:6 kcal/mol) than to the binding site 2 (-1249:0 kcal/mol). Considering that AgFAP1 nanopowder absorbs photons over all part of UV radiation spectrum, this material might be used as potential radiation protective nanomaterial.

AB  - Synthetic paths toward the two polymorphs of a monohydrate, one anhydrous polymorph of 1-carboxamidino-5-hydroxy-3-methylpyrazole (hcmp) and two polymorphs of zinc complexes containing hcmp ligand are presented. By choosing ions which are not part of the final product, it is possible to direct the synthesis toward the particular polymorph. In all three modifications of hcmp, the same hydrogen bonding motif appears, leading to formation of similar molecular chains. Differences arise due to different modes of chain aggregation and the presence of solvent water. Analysis of the crystal packing and the energetic features of hcmp polymorphs is made using the PIXEL model. The thermal decomposition processes are examined using differential scanning calorimetry and thermogravimetry. Analysis of crystal packing in the two polymorphs of zinc complex suggests the key role of the hydrogen bonding capacity of the aqua ligand for the appearance of the two polymorphic forms. In both polymorphs of zinc complex, stacking interactions have an important role. However, the enhanced hydrogen bonding capacity of the aqua ligand influences the formation of multistacking arrangement.

AB  - Silver doped fluorapatite nanopowders were synthesised by neutralization method, which consists of dissolving Ag2O in solution of HF and H3PO4 and addition to suspension of Ca(OH)(2). The powder XRD, SEM and FTIR studies indicated the formation of a fluorapatite nanomaterials with average length of the particles is about 80 nm and a width of about 15 nm. The FUR studies show that carbonate content in samples is very small and carbonte ions substitute both phosphate and hydroxyl groups in the crystal structure of samples, forming AB-type fluorapatite. Antibacterial studies have demonstrated that all Ag+-doped fluorapatite samples exhibit bactericidal effect against pathogens: Staphylococcus aureus, Micrococcus luteus and Kllebsiela pneumoniae. Antibacterial activity increased with the increase of Ag+ in the samples. The atomic force microscopy studies revealed extensive damage to the bacterial cell envelops in the presence of AW-doped fluorapatite particles which may lead to their death. The synthesized Ag+-doped fluorapatite nanomaterials are promising as antibacterial biomaterials in orthopedics and dentistry. (C) 2015 Elsevier B.V. All rights reserved.

AB  - The synthesis of a potentially bioactive mixed-valence Co-III/Co-II complex with 2-acetylpyridine S-methylisothiosemicarbazone (HL) ligand is described. The crystal and molecular structure of the formed [(CoL2)-L-III][(CoCl3)-Cl-II py]center dot Me2CO (I) compound (py stands for pyridine) is determined by single-crystal X-ray crystallography. It's thermal decomposition along with the decomposition of the ligand and six structurally related complexes with formulas [CoL2]NO3 center dot MeOH (1), [CoL2]Br center dot MeOH (2), [CoL2]HSO4 center dot MeOH (3), [CoL2](2)[Co-II(NCS)(4)] (4), [Co(HL)(L)]I-2 center dot 2MeOH (5), and [Co(HL)(L)][(CoCl4)-Cl-II]center dot MeOH (6) was determined by simultaneous TG/DSC measurements. The decomposition pattern is evaluated using TG/DTA-MS data. The results were related to the solvent/moisture content and the decomposition mechanism of the compounds. The antimicrobial activity of the ligand and of all the complexes was tested in vitro for selected gram-negative and gram-positive bacteria and fungi. The activity of the ligand against all tested bacteria is comparable with those obtained for standard antibiotics, while it is less active against fungi. Surprisingly, the activity of the complexes is very low. The low antimicrobial activity of the complexes may be in connection with their high thermodynamic and kinetic inertness in solution. The results are also supported by the relatively high thermal stability of the complexes.

AB  - New cationic Cu(II) and Co(II) complexes with N,N',N '',N'''-tetrakis(2-pyridylmethyl)-1,4,8,11-tetraazacyclotetradecane (tpmc) and the anion of 2-amino-3-phenylpropanoic acid (S-phenylalanine) were prepared. The complexes were analyzed and characterized by elemental analysis, conductometric, polarimetric, magnetic and cyclic voltammetric measurements, as well as by spectroscopic data (UV/Vis, IR). Both complexes are binuclear with the general formula [M(2)(S-Phe)tpmc](ClO(4))(3)center dot nH(2)O; S-PheH = S-phenylalanine, M(II) = Cu, n = 7; Co, n = 0. Based on previously reported data for some familiar complexes and the present results, pentacoordinated geometry was proposed. Both of the central metal ions are coordinated with two pyridyl and two cyclam nitrogens and bridged with -N-(CH(2))(3)-N-portions of the cyclam ring and oxygen atoms of the S-phenylalaninate ion. Antimicrobial screening of the complexes, solvent, starting salts and ligands alone was performed against fungi, mould and some bacteria. In certain cases, enhanced activity of Co(II) complex towards bacteria compared with the relevant free ligands and starting salts was detected.

AB  - Four new air-stable mixed-ligand Co(II) complexes having the general formula [Co(2)(Y)tpmc]Z(3)center dot q(H(2)O/CH(3)CN) (HY = N-methylglycine/N,N-dimethylglycine, Z = BF(4)(-), qH(2)O = 4 or 3; HY = S-norvaline/S-valine Z = ClO(4)(-), qCH(3)CN = 0.5; qH(2)O = 0.5; tpmc = N,N',N '',N'"-tetrakis(2-pyridymethyl)-1,4,8,11-tetraazacyclotetradecane) were prepared. The composition, some physical and chemical properties and their tentative geometries were evaluated based on elemental analysis (C, H, N), conductometric and magnetic measurernents, spectroscopic data (UV/Vis, IR) and cyclic voltammetry. The data were compared with earlier described analogous complexes containing the macrocyclic ligand and aliphatic aminocarboxylates. It is assumed that all complexes are binuclear with an exo coordination mode of the octaazarnacrocyclic pendant ligand in the boat conformation. In addition, two -N-(CH(2))(2)-N- portions of the cyclam ring within the tpmc ligand and Co(II) ions in the high-spin state are most probably bridged via oxygen atoms from the anion of the aminocarboxylate/derivatives, whereas nitrogen atoms rest uncoordinated. In all cases, a combined chelate-bridged coordination is proposed as the most probable. The complexes were electrochemically stable in the potential range -1.0 to 1.0 V. They were also preliminary assayed toward some microorganisms together with the ligands, starting simple salts and solvents as test substances. In some cases, certain antimicrobial activity of the complexes was detected.
AB  - Dobijena su četiri nova mešovito-ligandna kompleksa Co(II), stabilna na vazduhu, opšte formule [Co2(Y)tpmc]Z3×q(H2O/CH3CN) (HY = N-metilglicin/N,N-dimetilglicin, Z=-4BF , qH2O=4 ili 3); HY = S-norvalin/S-valin, Z=-ClO4, qCH3CN=0,5; qH2O=0,5; tpmc= N,N',N'',N'''-tetrakis(2-piridilmetil)-1,4,8,11-tetraazaciklotetradekan). Sastav, neka fizička i hemijska svojstva i njihove približne geometrije su izvedene na osnovu elementalne analize (C, H, N), konduktometrijskih i magnetnih merenja, spektroskopskih podataka (UV/Vis, IR) odnosno ciklične voltametrije. Podaci su upoređeni sa ranije opisanim analogim kompleksima koji sadrže makrociklični ligand i alifatične aminokarboksilate. Pretpostavljeno je da su svi kompleksi dinuklearni sa egzo koordinacijom pendantnog oktaazamakrocikla u konformaciji lađe. Pored dva -N-(CH2)2-N- dela ciklamovog prstena unutar tpmc-a, joni visoko-spinskog Co(II) su najverovatnije premošćeni angažovanjem kiseonikovih atoma sa anjona aminokarboksilata/derivata, dok atomi azota ostaju nekoordinovani. Za sve komplekse predložen je kombinovani helatno-mostovni način vezivanja. Kompleksi su bili elektrohemijski stabilni u opsegu potencijala -1,0 do 1,0 V. Oni su preliminarno testirani na mikroorganizme zajedno sa ligandima, polaznim prostim solima i rastvaračima kao test supstancama. U nekim slučajevima je nađena izvesna antimikrobna aktivnost kompleksa.

AB  - Saturated aqueous solutions of 28 different salts have been studied as a potential mobile phases for salting-out thin-layer chromatography, on silica gel, of a series of four mixed bis-aminocarboxylato cobalt(III) complexes. In addition, by linear regression analysis of chromatographic data obtained for fifteen mixed aminocarboxylato Co(III) complexes (four series) with solutions of ammonium chloride, three alkali metal chlorides, and four alkaline earth metal chlorides, four linear dependences previously established on different adsorbents with (NH4)(2)SO4 solutions were confirmed. The qualities of the separations achieved with the salts were compared and Li+, Mg2+, and Ca2+ chlorides are proposed as the most suitable.

AB  - Silica gel impregnated with poly(ethylene glycol) of different molecular mass (400, 1000, 1540, 4000, and 5500) was investigated for salting-out thin-layer chromatography of 15 mixed aminocarboxylato Co(III) complexes using eight ammonium sulphate solutions as mobile phases. Regularities established earlier for non-impregnated adsorbents are also valid in this work. Poly(ethylene glycol) of high molecular mass increases the hydrophobicity of the adsorbent. Positive linear dependence of R-M values and of salting-out efficiency on average poly(ethylene glycol) molecular mass was usually observed. In contrast with non-impregnated silica gel, separation was achieved between complexes with the smallest hydrocarbon groups.
