20.500.12556/RUL-113326 Nikljeve(II) spojine z anionom benzojske kisline Nickel compounds with benzoic acid anion Sintetizirala sem tri različne nikljeve(II) koordinacijske spojine z anionom benzojske kisline [Ni(C7H5O2)(H2O)2](C7H5O2)(H2O) 1, [Ni(C7H5O2)2(C6H6N2O)2(H2O)2] 2 in [Ni(C7H5O2)2(C5H6N2)2] 3. Kot topilo sem pri sintezah uporabila etanol in destilirano vodo. Uporabila sem tudi benzojsko kislino (C7H6O2), ki se je vezala kot anion. Kot dodatni nevtralni ligand sem dodala nikotinamid (C6H6N2O) ter 2-aminopiridin (C5H6N2). V virih sem poiskala podatke o teh spojinah ter jih primerjala s svojimi. Z rentgensko praškovno analizo sem ugotovila istovetnost mojih spojin z znanimi spojinami, čeprav so se sintezne poti deloma razlikovale. Potrditev le tega je sledila tudi z elementno analizo. Prisotnost zapisanih sestavnih enot spojin sem opazovala z IR spektroskopijo. Spreminjanje koordinacijske sfere sem ocenjevala z UV-Vis spektroskopijo. Prisotnost dveh nesparjenih elektronov v vseh tu opisanih spojinah se sklada z vrednostmi magnetizma za Ni(II) zvrsti. Synthesized were three different nickel(II) coordination compounds with an anion of benzoic acid. These are [Ni(C7H5O2)(H2O)2](C7H5O2)(H2O) 1, [Ni(C7H5O2)2(C6H6N2O)2(H2O)2] 2 and [Ni(C7H5O2)2(C5H6N2)2] 3. Ethanol and distilled water were used as syntheses’ solvents. Benzoic acid (C7H5O2) was also used binded as anion. Nicotinamide (C6H6N2O) and 2-aminopyridine (C5H6N2) were applied as the additional neutral ligand. The data on these compounds were found in literature and compared to my experimental data on the titled ones. Using X-ray powder diffraction analysis, the identity with the reported compounds were confirmed although the synthetic routes partly differ. Additional confirmation for these data was obtained with the elemental analysis. A presence of the compounds’ ligands was confirmed with the IR spectroscopy. The coordination sphere changes were checked with the UV–Vis spectroscopy. Two unpaired electrons in all the compounds described herein are consistent with the magnetism expectations for the Ni(II) species. nikelj(II) benzojska kislina nikotinamid 2-aminopiridin nikljev(II) nitrat(V) heksahidrat nickel(II) benzoic acid nicotinamide 2-aminopyridine nickel(II) nitrate(V) hexahydrate true false false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2019-12-20 11:50:01 2019-12-20 11:50:05 2022-08-25 03:55:50 0000-00-00 00:00:00 2019 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 5999 1538508483 Petric_Marusa_-_Nikljeve_spojine_z_benzojsko_kislino.pdf Petric_Marusa_-_Nikljeve_spojine_z_benzojsko_kislino.pdf 1 2F6B09B32CBF48B420A42A85979ED05A b6f1a2f8f2565ef0e1aae2166c6467db5948b58c18be27c84abfb5548047d19f 1301c786-a1b8-11eb-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=125373 Fakulteta za kemijo in kemijsko tehnologijo 0 0 0
