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  - Dobijena su dva nova kompleksa Cu(II) i Co(II) sa N,N',N',N'''-tetrakis(2-piridilmetil)-1,4,8,11-ciklotetradekanom (tpmc-om) i anjonom 2-amino-3-fenil-propanske kiseline (S-fenilalanina). Oni su analizirani i okarakterisani: elementalnom analizom, konduktometrijskim, polarimetrijskim, magnetnim i ciklično-voltametrijskim merenjima, kao i spektroskopskim podacima (UV/Vis, IR). Oba kompleksa su dinuklearna opšte formule [M2(S-Phe)tpmc](ClO4)3·nH2O; S-PheH = S-fenilalanin, M(II) = Cu, n = 7; Co, n = 0. Na osnovu ranije dobijenih podataka za srodne komplekse i novih rezultata pretpostavljena je pentakoordinaciona geometrija. Oba centralna metalna jona su koordinovana za po dva piridil i dva ciklamova azota i premošćena -N-(CH2)3-N-fragmentima ciklamovog prstena i kiseonikovim atomima S-fenilalaninato jona. Antimikrobni test kompleksa, rastvarača, polaznih soli i samih liganada je izvršen na gljivice, plesni i bakterije. U izvesnim slučajevima nađena je povećana aktivnost kompleksa Co(II) prema pojedinim bakterijama u odnosu na odgovarajuće slobodne ligande i polazne soli.

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.
