20.500.12556/RUL-161280 Ksantin kot ligand v koordinacijskih spojinah Xanthine as ligand in coordination compounds Izvedel sem reakcije med ligandom ksantinom in kovinskimi ioni prehoda, kot so Ni(II), Co(II), Cu(II), Cd(II), Zn(II) in Pb(II), ob dodatku KSCN. Reakcije so bile izvedene v metanolu in vodi s segrevanjem na oljni kopeli. Pri dveh reakcijah je nastala koordinacijska spojina, v eni so se na cinkov ion koordinirali štirje tiocianatni ioni, v drugi pa so se na cinkov ion koordinirali štirje ligandi, dve molekuli ksantina in dva kloridna iona. Obe spojini sta že opisani v literaturi. Nastale kristalinične produkte sem analiziral z IR spektroskopijo, 1H NMR spektroskopijo in rentgensko strukturno analizo. This bachelor’s thesis describes different reactions between the ligand xanthine and transition metal ions such as Ni(II), Co(II), Cu(II), Cd(II), Zn(II) and Pb(II) with the addition of KSCN. The reactions were carried out in methanol and water by using an oil bath. Two of the reactions produced a coordination compound, in one four thiocyanate ions coordinated around the zinc, in the other two xanthine molecules coordinated around the zinc along two chloride ions. Both compounds have already been described in the literature. The resulting crystalline products were analyzed by IR spectroscopy, 1H NMR spectroscopy and X-ray structural analysis. ksantin koordinacijska spojina infrardeča spektroskopija rentgenska strukturna analiza xanthine coordination compound infrared spectroscopy X-ray structural analysis true false false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2024-09-09 10:17:24 2024-09-09 10:17:26 2024-09-20 12:15:59 0000-00-00 00:00:00 2024 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 24275 208318723 Levstek_Jaka_-_Ksantin_kot_ligand_v_koordinacijskih_spojinah.pdf Levstek_Jaka_-_Ksantin_kot_ligand_v_koordinacijskih_spojinah.pdf 1 3BDAEE09D69C04B80E74EC83BD4A9243 24f11693e0517d31ead7bce94c66d3202c71dd02f5f7ebabe47e54ab5cc8ba8d e99eac14-6e83-11ef-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=190175 Fakulteta za kemijo in kemijsko tehnologijo 0 0 0
