Izvedla sem reakcije med N-etoksikarbonil-N'-(3-metilpiridin-2-il)tiosečnino kot ligandom in Cu(II), Ni(II), Cd(II), Zn(II) ter Co(II) ioni ter z dodatkom MeONa in/ali KSCN v reakcijski zmesi. Reakcije so potekale v metanolu kot topilu ob segrevanju in intenzivnem mešanju. Nastalo je šest različnih produktov. Reakcije Cd(II), Zn(II) in Co(II) z ligandom niso potekle. Ligand pa se je uspešno koordiniral na Ni(II) in Cu(II) ione. Pri reakcijah s Cu(II) ioni in ligandom sta poleg koordinacijske spojine nastali še dve spojini, kjer je prišlo do oksidativne ciklizacije liganda in je nastal 2-((etoksikarbonil)amino)-8-metil-[1,2,4]tiadiazolo[2,3-a]piridin-4-ijev kation. Nastale produkte sem okarakterizirala z IR spektroskopijo, 1H NMR spektroskopijo, rentgensko strukturno analizo in elementno analizo.

Coordination compounds with N-ethoxycarbonyl-N'-(3-methylpyridine-2-yl)thiourea as ligand |
Sekundarni povzetek: |
Reactions between N-etoxycarbonyl-N'-(3-methylpyridine-2-yl)-thiourea, as ligand, and Cu(II), Ni(II), Cd(II), Zn(II) and Co(II) ions with addition of MeONa and/or KSCN were performed. The reactions were carried out in methanol as solvent, with heating and vigorous stirring. Six different products were created. Reactions between Zn(II), Co(II), Cd(II) ions and ligand did not occur. The ligand was successfully coordinated to Ni(II) and Cu(II) ions. Reactions with Cu(II) ions and the ligand, alongside to the coordination compound, two other compounds were formed, where oxidative cyclization of the ligand occurred and 2-((ethoxycarbonyl)amino)-8-methyl-[1,2,4]thiadiazolo[2,3-a]pyridin-4-ium cation was formed. The resulting products were characterized by IR spectroscopy, 1H NMR spectroscopy, X-ray structural analysis and elemental analysis. |
