Sinteza in strukturna karakterizacija spojin iz ternarnega sistema CuBr-HBr-voluminozni poliamin

Zakošek, Žan (author), Golobič, Amalija (mentor), Goreshnik, Evgeny (comentor)

Opravil sem sistematično raziskavo ternarnega sistema CuBr - HBr - DABCO. Za pripravo novih spojin v izbranem ternarnem sistemu sem pripravil različna razmerja začetnih reaktantov (HBr, CuBr$_2$, DABCO) in izvedel elektrokemijsko (v acetonitrilu in etanolu) in solvotermalno (v acetonitrilu) sintezo izbranih razmerij. S pomočjo rentgenske difrakcije na monokristalih sem določil 7 novih kristalnih struktur v izbranem sistemu. Za vsako sintezo posebej sem izrisal graf ternarnega sistema CuBr - HBr - DABCO, v katerem sem označil pripravljena razmerja in faze, ki sem jih dobil v posamezni točki. Poleg željenih produktov sem hkrati določil še 7 novih kristalnih struktur stranskih produktov. Vse nove kristalne strukture predstavljene v tej magistrski nalogi sem naložil v CSD (Cambridge Structural Database).

Abstract

I performed systematic investigation of ternary system CuBr - HBr - DABCO. For preparation of new compounds in the ternary system, I prepared different ratios of starting reactants (HBr, CuBr$_2$, DABCO) and performed electrochemical (in acetonitrile and ethanol) and solvothermal (in acetonitrile) synthesis. With single crystal X-ray diffraction, I determined 7 new crystal structures from the ternary system in question. For each synthesis procedure, I draw a graph of ternary system CuBr - HBr - DABCO in which, I marked prepared ratios and phases that were obtained in individual spots of the graph. I was also able to determine 7 new crystal structures of byproducts. All new crystal structures presented in this master thesis were deposited to CSD (Cambridge Structural Database).
