Nikljeve spojine s pirazinojsko kislino

diplomsko delo

Tina Boh (Author), Saša Petriček (Mentor)

Abstract

Izvedli smo več reakcij med nikljevim(II) kloridom ali nikljevim(II) sulfatom heptahidratom in pirazinojsko kislino v različnih topilih ali mešanicah le teh. V nekaterih primerih smo v reakcijsko zmes dodali še koncentrirano klorovodikovo ali žveplovo kislino. Reakcije so potekale pri sobni temperaturi oz. med segrevanjem pri temperaturi 60 °C na oljni kopeli. Nastala je svetlo zelena koordinacijska spojina [NiCl$_2$(pyzaH)$_2$] in zmes nikljevih(II) kompleksov s pirazinoatom. Vse izolirane produkte smo analizirali z različnimi fizikalno-kemijskimi tehnikami. Posneli smo IR spektre in opravili CHN, termično in rentgensko praškovno analizo.

Secondary abstract:	In our study, several reactions were performed between nickel(II) chloride or nickel(II) sulfate heptahydrate and pyrazinoic acid in various solvents or solvent mixtures. In some cases, concentrated hydrochloric acid or sulfuric acid was added to the reaction mixture. The reactions were carried out at room temperature or by heating at 60 °C in an oil bath. The reactions resulted in the formation of the light green coordination compound, [NiCl$_2$(pyzaH)$_2$] and a mixture of nickel(II) complexes with pyrazinoate. All isolated products were analyzed using different physicochemical techniques. IR spectra were recorded for all products and CHN, thermal and powder X-ray diffraction analyzes were performed for some of them.
