Abstract

Namen diplomske naloge je bil sintetizirati koordinacijske spojine iz bakra, kobalta in niklja ter melamina, z uporabo različnih topil. V eksperimentalnem delu smo izvedli 15 sintez koordinacijskih spojin. Sintetizirali smo bakrove komplekse iz bakrovega(II) acetata in bakrovega klorida, nikljeve komplekse iz nikljevega(II) acetata in kobaltove komplekse iz kobaltovega(II) acetata z ligandom melaminom. Uporabljali smo različna topila in sicer: metanol, etanol, vodo in dimetilformamid. Sinteze smo izvajali pod refluksom 3 ure, eno smo izvajali z podaljšanim reakcijskim časom in sicer 6 ur. Na koncu smo nastale produkte še analizirali z rentgensko praškovno difrakcijo in termogravimetrično analizo ter tako ugotavljali uspešnost izvedenih sintez. Iz rezultatov smo ugotovili, da s podaljšanim časom ne vplivamo na potek reakcij oziroma na sintezo. Prav tako smo ugotovili, da pri uporabi vode kot topila ne dobimo željenih rezultatov.

Secondary title:	SYNTHESIS AND CHARACTERIZATION OF COORDINATION COMPOUNDS OF TRANSITION METALS WITH MELAMINE
Secondary abstract:	Tha aim of this diploma work is to synthesize coordination compounds from copper, cobalt, nickel and also of melamine, with usage of different solvents. In experimental part we made 15 coordination compound syntheses. We synthesized cupric complexes from cupric acetate and cupric chloride, nickel complexes from nickel acetate and cobalt complexes from cobalt acetate with mixed ligand. We used different solvents: methanol, ethanol, water and dimethylformamide. We were performing synthesis under reflux for 3 hours, we carried out one for extended reaction time – 6 hours. In the end we analysed new products with X-ray powder diffraction and thermogravimetric analysis and we measured the success of performed syntheses. We found out that with extended time we do not influence on the course of reactions or on the syntheses. We also found out that we do not get the expected results with usage of water as a solvent.
