Abstract

Izvedene so bile reakcije 1-(piridin-2-il)tiosečnine z izbranimi kovinami prehoda, pri čemer je bil poudarek na sintezi koordinacijskih spojin, v katerih bi bila prisotna 1-(piridin-2-il)tiosečnina kot ligand. Skupaj je bilo izvedenih 13 reakcij, pri čemur sta bila v vsaki prisotna 1-(piridin-2-il)tiosečnina (L) in KSCN, menjavale pa so se soli prehodnih kovin. Uporabljeni so bili sledeči kovinski ioni: Ni2+, Pb2+, Zn2+, Cd2+, Co2+, Fe3+ in Fe2+. Po opravljenih sintezah so bili nastali kristali analizirani z rentgensko strukturno analizo. Vsi produkti pa so bili analizirani še z NMR in IR. Iz opravljenih analiz lahko sklepam, da sem uspel sintetizirati štiri nove koordinacijske spojine in sicer [NiL4(NCS)2], [Pb(CH3COO)L(NCS)]n, [CdL2(NCS)2]n in [ZnL2(NCS)2]. Med produkti so bili opaženi tudi elementno žveplo, KNO3 in 1-(piridin-2-il)tiosečnina, ki je kristalizirala v drugačni osnovni celici od že znane in objavljene.

Secondary title: Coordination compounds with 1-(pyridin-2-yl)thiourea as ligand
Secondary abstract: Reactions between 1-(pyridine-2-yl)thiourea and selected transition metals were performed as a method to synthesize coordination compounds that would contain 1-(pyridine-2-yl)thiourea as a ligand. In total 13 reactions were performed, with 1-(pyridine-2-yl)thiourea (L) and KSCN participating in all of them and transition metal salts being swapped. The following metal ions were used: Ni2+, Pb2+, Zn2+, Cd2+, Co2+, Fe3+ and Fe2+. After synthesis was done, crystals were analysed with X-ray structural analysis. All products were also analysed with NMR and IR analysis. According to the analyses performed, I can conclude that four new coordination compounds were obtained which were [NiL4(NCS)2], [Pb(CH3COO)L(NCS)]n, [CdL2(NCS)2]n and [ZnL2(NCS)2]. Elemental sulfur, KNO3 and 1-(pyridine-2-yl)thiourea that crystallized in a different unit cell than previously known and published were also observed in some reactions.
