20.500.12556/DKUM-65921 Sinteza in karakterizacija nikljevih koordinacijskih spojin z izbranimi tiopiridinskimi ligandi Synthesis and characterization of coordination compounds with nickel using thiopyridine ligands Namen magistrskega dela je bila sinteza novih koordinacijskih spojin z nikljem. Pri tem je bil uporabljen nikljev acetat tetrahidrat in različni tiopiridinski ligandi. Opravljenih je bilo 36 sintez. Sinteze so bile v največji meri izvedene z mešanjem pri sobni temperaturi, v določenih primerih pa z refluktiranjem in solvotermalno pri povišani temperaturi in tlaku. Kot topili sta bila v večini primerov uporabljena metanol in N,N-dimetilformamid. Pogosto smo uporabili tudi ustrezno kombinacijo topil. Dobljeni sintezni produkti so bili karakterizirani z infrardečo spektroskopijo, rentgensko analizo na monokristalu in rentgensko praškovno difrakcijo. Dodatne informacije o strukturi in lastnostih spojin smo pridobili z magnetnimi meritvami in s termogravimetrično analizo. V okviru magistrskega dela je bila uspešno sintetizirana do sedaj še neznana koordinacijska spojina s kemijsko formulo: [Ni(O2CCH3)2(C7H6N2S)2]. Gre za enojedrno koordinacijsko spojino z nikljem, na katerega sta vezana dva enovezna liganda, molekuli 2-aminobenzotiazola in dva kelatno vezana acetatna liganda. Sinteza je bila izvedena z mešanjem pri sobni temperaturi, na zraku. Kot topilo je bil uporabljen metanol. The purpose of this dissertation was the synthesis of new coordination compounds of nickel. We used nickel acetate tetrahydrate and different thiopyridine ligands. To achieve our goal, we performed thirty-six synthesis reactions. In most cases reactions were carried at room temperature on a stirrer, under reflux or solvothermal at high temperature and high pressure. Our solvents were mainly methanol and N,N-dimethylformamide. Several times we also used appropriate combinations of solvents. The compounds were then characterized by infrared spectroscopy, by single-crystal X-ray diffraction and by X-ray powder diffraction. Additional structural information and information about properties were obtained by magnetic measurements and thermogravimetric analysis. We have successfully synthesized a new, previously unreported coordination compound with chemical formula [Ni(O2CCH3)2(C7H6N2S)2]. Given compound is mononuclear coordination compound of nickel, with two chelating acetate ligands and two monodentate ligands, molecules of 2-aminobenzothiazole. New compound was synthesized at room temperature, in air. As solvent, we used methanol. koordinacijska spojina nikelj tiopiridinski ligandi 2-aminobenzotiazol Fourierjeva transformacijska infrardeča spektroskopija termogravimetrična analiza monokristalna analiza rentgenska praškovna difrakcija magnetizem coordination compound nickel thiopyridine ligands 2-aminobenzothiazole Fourier transform infrared spectroscopy thermogravimetric analysis single crystal X-ray structure analysis X-ray powder diffraction magnetism true true false [K.
