20.500.12556/RUL-164511 Nikljeve spojine s pirazinojsko kislino Nickel compounds with pyrazinoic acid 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. 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. nikelj pirazinojska kislina koordinacijske spojine nickel pyrazinoic acid coordination compounds true false false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2024-10-29 07:30:01 2024-10-29 07:30:09 2024-12-12 13:22:18 0000-00-00 00:00:00 2024 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 24245 218814979 Boh_Tina_-_Nikljeve_spojine_s_pirazinojsko_kislino.pdf Boh_Tina_-_Nikljeve_spojine_s_pirazinojsko_kislino.pdf 1 6203DDF7AB9655CAC2E40DC27CDB35FC c0cb5bb749542df1b299b55e236cbc384a95d953fc59c1bb2bd414c807cd46c1 ee8bb2a4-95be-11ef-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=194990 Fakulteta za kemijo in kemijsko tehnologijo 0 0 0
