20.500.12556/RUL-129655 Priprava in karakterizacija koordinacijskih spojin kobaltovega(II) nitrata in 2-(hidroksimetil)piridina Synthesis and characterization of coordination compounds of cobalt(II) nitrate and 2-(hydroxymethyl)pyridine Izvedli smo več reakcij med kobaltovim(II) nitratom heksahidratom in ligandom 2-(hidroksimetil)piridinom ob različnih množinskih razmerjih reaktantov v izbranih topilih: acetonu in acetonitrilu. Pripravili smo dve novi spojini [Co(OH2)2(2hmp)2](NO3)2 in [Co(2hmp)3](NO3)2. V primeru nastanka kompleksa, kjer je množinsko razmerje ligand:kovina 3:1, so se pojavili tudi kristali solvata. Nastale produkte smo okarakterizirali z infrardečo spektroskopijo, elementno CHN analizo, termogravimetrijo in rentgensko praškovno difrakcijo ter jim določili kristalno strukturo z difrakcijo na monokristalu. V primeru nastanka solvata smo zaradi njegove nestabilnosti lahko določili le kristalno strukturo. Several reactions using different molar ratios of cobalt(II) nitrate hexahydrate and 2-(hydroxymethyl)pyridine in selected solvents (acetone and acetonitrile), were performed. Two new compounds, [Co(OH2)2(2hmp)2](NO3)2 and [Co(2hmp)3](NO3)2, have been prepared. When compound with ligand to metal molar ratio of 3:1 was synthetized, solvate crystals were also formed. The products were characterized by infrared spectroscopy, CHN elemental analysis, thermogravimetry and Xray powder diffraction, crystal structure determination from single-crystal diffraction data was also performed. In case of unstable solvate compound, only its crystal structure was determined. kobalt 2-(hidroksimetil)piridin monokristal koordinacijske spojine cobalt 2-(hydroxymethyl)pyridine single crystal coordination compounds true false false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2021-09-06 12:42:07 2021-09-06 12:42:08 2022-09-08 04:09:53 0000-00-00 00:00:00 2021 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 14921 76018691 Peckaj_Anja_-_Priprava_in_karakterizacija_koordinacijskih_spojin_kobaltovega(II)_nitrata_in_2-(h.pdf Peckaj_Anja_-_Priprava_in_karakterizacija_koordinacijskih_spojin_kobaltovega(II)_nitrata_in_2-(h.pdf 1 A66B9DC23FC19C577F25EB758EF40B73 297bd7aa75c53b2b95f7e1519139e24b957cd1ece1c996a9e02da030e4d384f1 d7a6ee2d-0efe-11ec-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=146671 Fakulteta za kemijo in kemijsko tehnologijo 0 0 0
