Abstract:	V magistrskem delu opisujemo sintezo in karakterizacijo novih bakrovih koordinacijskih spojin, za sintezo katerih smo kot vir bakra uporabili bakrove soli, kot vir ligandov pa piridinkarbonitrile. Opisali smo tudi sintezo in karakterizacijo nekaterih že poznanih struktur, ki nam jih je uspelo sintetizirati. Sintetizirali smo štiri nove koordinacijske spojine: [Cu2(μ-Ac)4(3-PCN)2], [Cu(H2O)(NO3)(PIC)2]NO3, [Cu(H2O)2(EtPIC)2]NO3 in [Cu(NO3)2(CH3CN)(4-PCN)]·CH3CN. Poleg teh nam je uspelo sintetizirati tudi nekaj že znanih spojin, kot so: [Cu 2(C2H3O2)4(C6H4N2)2], fg in rtger. Prvo spojino, [Cu2(μ-Ac)4(3-PCN)2], smo v vodnem okolju sintetizirali iz bakrovega(II) acetat monohidrata in 3-piridinkarbonitrila. Drugo in tretjo spojino, [Cu(H2O)(NO3)(PIC)2]NO3, [Cu(H2O)2(EtPIC)2]NO3, smo sintetizirali iz bakrovega(II) nitrat trihidrata in 2-priridnkarbonitrila. Razlika je bila v uporabi topila. Pri prvi spojini smo uporabili vodo, pri drugi pa etanol. Zadnjo še ne odkrito spojino, [Cu(NO3)2(CH3CN)(4-PCN)]·CH3CN, smo sintetizirali iz bakrovega(II) nitrat trihidrata in 4-piridinkabonitrila. Kot topilo smo uporabili acetonitril. Sinteze smo izvajali pri sobni temperaturi in s pomočjo refluksa, pri temperaturi vrelišča uporabljenega topila. Molekulske strukture kompleksov smo determinirali z rentgensko difrakcijo na monokristalu izvedli pa smo tudi infrardečo spektroskopijo, termogravimetrično analizo in diferenčno dinamično kalorimetrijo.

Title:	Synthesis of copper coordination compounds with pyridinecarbonitriles
Abstract:	In the master's thesis, we describe the synthesis and characterization of new copper coordination compounds, using copper salts as the source of copper and pyridine carbonitriles as the source of ligands. We also described the synthesis and characterization of some known structures that we managed to synthesize. We synthesized four new coordination compounds: [Cu2(μ-Ac)4(3-PCN)2], [Cu(H2O)(NO3)(PIC)2]NO3, [Cu(H2O)2(EtPIC)2]NO3, and [Cu(NO3)2(CH3CN)(4-PCN)]·CH3CN. In addition to these, we also succeeded in synthesizing several known compounds, such as [Cu 2(C2H3O2)4(C6H4N2)2], fg, and rtger. The first compound, [Cu2(μ-Ac)4(3-PCN)2], was synthesized in an aqueous environment from copper(II) acetate monohydrate and 3-pyridinecarbonitrile. The second and third compounds, [Cu(H2O)(NO3)(PIC)2]NO3 and [Cu(H2O)2(EtPIC)2]NO3, were synthesized from copper(II) nitrate trihydrate and 2-pyridinecarbonitrile. The difference was in the solvent used. Water was used for the first compound, and ethanol was used for the second. We synthesized the yet-to-be-discovered compound, [Cu(NO3)2(CH3CN)(4-PCN)]·CH3CN, from copper(II) nitrate trihydrate and 4-pyridinecarbonitrile, using acetonitrile as the solvent. The syntheses were carried out at room temperature and using reflux at the boiling point of the solvent. We determined the molecular structures of the complexes through single-crystal X-ray diffraction. We also performed infrared spectroscopy, thermogravimetric analysis, and differential scanning calorimetry.
