AB  - Због своје могућности да оствари координационе бројеве од 2 до 9, високе биодоступност и афинитета према N, O, S-донорским атомима, Zn(II) се користи за синтезе комплекса у циљу њихове специфичне примене. У Кембричкој структурној бази података је депоновано само осам кристалних структура комплекса Zn(II), Cd(II) и Co(III) са 
N-хетероароматичним 1,3-селеназолил-хидразонским лигандима. У овом раду је  фокус био на кристалној структури комплекса Zn(II) са лигандом HLSe2 (2-Cl-Se; Слика 1). Молекулска и кристална структура новог комплекса 2-Cl-Se је упоређена са претходно објављеним Zn(II) комплексом са лигандом HLS2 (2-Cl), структурним аналогом лиганда HLSe2 [1]. Праћен утицај изостерне S/Se замене на топологију и енергетску дистрибуцију интермолекулских интеракција у Zn(II) комплексима са 1,3-селеназолил/тиазолил-хидразонима на бази пиридина.
AB  - Due to its ability to achieve coordination numbers from 2 to 9, high bioavail-ability, and affinity to N, O, and S-donor atoms, Zn(II) is used for the syn-thesis of complexes with the aim of their specific application. Only eight crystal structures of Zn(II), Cd(II), and Co(III) complexes with N-heteroaromatic 1,3-selenazolyl-hydrazone ligands are deposited in the Cam-bridge Structural Database. This work focused on the crystal structure of the Zn(II) complex with the HLSe2 ligand (2-Cl-Se; Figure 1). The molecular and crystal structure of the new 2-Cl-Se complex was compared with the previ-ously published Zn(II) complex with the HLS2 ligand (2-Cl), a structural analog of the HLSe2 ligand [1]. The influence of isosteric S/Se substitution on the topology and energy distribution of intermolecular interactions in Zn(II) complexes with pyridine-based 1,3-selenazolyl/thiazolyl-hydrazones was monitored [1].

AB  - Јефтина, нискотоксична координациона једињења Zn(II) представљају обећавајуће кандидате за различите примене, укључујући фотолуминесцентне материјале. У овом раду су представљена два комплекса Zn(II) са хидразонил-тиазолским лигандима на бази пиридина (HLS1 и HLS2), који су синтетсани директном реакцијом лиганaда и Zn(CH3COO)2∙2H2O. Пентануклеарни комплекс [Zn5(HLS1)4(CH3COO)6] (1-AcO; Слика 1) кристалише у моноклиничној P21/n просторној групи са половином молекула по асиметричној јединици, при чему се централни јон Zn(II) налази на центру инверзије (Викофово слово c). Мононуклеарни комплекс [Zn(HLS2)(CH3COO)(H2O)] (2-AcO; Слика 2) кристалише у триклиничној P¬–1 просторној групи са једним молекулом по асиметричној јединици. Експеримент дифракције X-зрака са узорка праха je потврдио да су добијени једнофазни производи. Урађена је детаљна анализа типова и енергетске дистрибуције интермолекулских интеракција. Симетричан комплекс 1-AcO није фотолуминесцентан, за разлику од комплекса 2-AcO. Квантно-механички прорачуни теорије функционала густине (DFT) и временски зависне теорије функционала густине (TD-DFT) су расветлили порекло фотолуминесцентних својстава комплекса 2-AcO.
AB  - Inexpensive, low-toxic Zn(II) coordination compounds are represent promising candidates for various applications, including photoluminescent materials. In this study we report two zinc(II) complexes with thiazolyl-hydrazone-based ligands (HLS1 and HLS2), which were synthesized by direct reaction of the ligands with Zn(CH3COO)2∙2H2O. Pentanuclear complex [Zn5(HLS1)4(CH3COO)6] (1-AcO; Figure 1) crystalizes in monoclinic P21/n space group with half of the molecule in the asymmetric unit, where Zn3 atoms lie at inversion center (Wyckoff letter c). Mononuclear [Zn(HLS2)(CH3COO)(H2O)] (2-AcO; Figure 2) crystalizes in triclinic P‒1 space group with one molecule in the asymmetric unit (Figure 2). Powder X-ray diffraction experiments confirmed that single-phase products were obtained. A detailed analysis of types and energy distribution of intermolecular interactions was performed. The symmetrical 1-AcO does not exhibit photophysical properties, unlike asymmetrical 2-AcO. Quantum-mechanical calculations of density functional theory (DFT) and time-dependent DFT provided insight into origin of the photoluminescent properties of 2-AcO.

AB  - Sintetisana su i strukturno okarakterisana dva nova komplesa Zn(II) sa tiazolil-hidrazonskim ligandima HLS1 i HLS2. Iako su tokom sinteze primenjeni isti reakcioni uslovi, korišćena ista polazna so ZnCl2·2H2O i strukturno veoma slični ligandi, dobijeni su kompleksi različitih geometrija. Koordinacioni broj kompleksa 1-Cl sa HLS1 ligandom je pet, a geometrija je distorgovana kvadratna piramida (Slika 1). Kompleks 2-Cl ima koordinacioni broj šest i distorgovanu oktaedarsku geometriju (Slika 2). Molekulsku strukturu kompleksa 1-Cl čini centralni jon metala, jedan ligand (HLS1) koordinovan tridentatno preko NNN donorskih atoma piridina, imino grupe i 1,3-tiazolovog prstena, kao i dva koordinovana hloridna jona. Dobijeni kompleks je neutralan. Kod kompleksa  2-Cl za centralni jon metala su kooridnovana dva HLS2 liganda  u neutralnom obliku, na isti način kao u slučaju kompleksa 1-Cl, što za posledicu ima formiranje katjonskog kompleksa čije je pozitivno naelektrisanje neutralisano ZnCl42– jonom. Kompleksi kristališu u monokliničnom kristalnom sistemu, ali u različitim prostornim grupama (1-Cl: P21/c i 2-Cl: C2/c). U kompleksu 2-Cl joni metala se nalaze u specijalnom položaju na osi 2 (Vikofov položaj e). Kristalno pakovanje oba kompleksa se zasniva na klasičnim N–H/Cl interakcijama. Eksperimenti difrakcije praha oba kompleksa potvrdili su da su dobijeni jednofazni proizvodi.
AB  - Two novel Zn(II) complexes with thiazolyl-hydrazones ligands HLS1 and HLS2, have been synthesized and characterized. Although the syntheses were performed under the same reaction conditions, using the same starting salt ZnCl2·2H2O and structurally very similar ligands, the geometries of the obtained complexes are different. The coordination number of the complex 1-Cl with HLS1 is five and the geometry is distorted square pyramidal (Figure 1). The complex 2-Cl has coordination number six and distorted octahedral geometry. Thus, the molecular structure of complex 1-Cl consists of one metal center, one HLS1 ligand coordinated tridentately via NNN atoms from pyridine, imine and 1,3-thiazole ring and two coordinated chloride ions. The obtained complex is neutral. The structure of complex 2-Cl consists of one metal center, two HLS2 ligands coordinated in the same way as in the previous complex. In this case the cationic complex is formed and the charge is balanced by ZnCl42–. Both complexes crystallize in a monoclinic crystal system, but in the different space groups (1-Cl: P21/c and 2-Cl: C2/c). Metal ions in 2-Cl are residing on a special position with site symmetry 2 (Wyckoff leter e). The crystal packing of these complexes is based on classical N–H/Cl hydrogen interactions. Powder X-ray diffraction experiments confirmed the presence of a single phase in both samples

AB  - Despite the variety in coordination polymers’ (CP) structure their characteristic architecture is based on relatively small organic molecules, which are most often O or N donors [1]. The ligand piperazine 1,4-dicarbonitrile (L) is used for synthesis of novel Ag(I) 3D CP with general formula {[Ag(L)2]ClO4}n. The obtained complex crystallizes in the orthorhombic crystal system, space group Pnnn. The structure of CP consists of one metal center, two L ligands coordinated bismonodentately via N atom and one perchlorate anion (Figure 1). Each Ag(I) is in tetrahedral environment, coordinated to four nitgoren atoms from four different L ligands. The geometric index of distortion is 0.956 [2]. Topological analysis [3] showed that there are  two crystallographically different Ag(I) ions. The first one builds two interpenetrating networks which are related by 12.61 Å translations along the a-axis direction (class Ia). The second Ag(I) ion gives four interpenetrating networks related by 12.61 Å translations along the a-axis direction and by an inversion centre (class IIIa).
