Abstract

U sklopu ovog diplomskog rada istražena je mogućnost nastajanja koordinacijskih spojeva
nikla(II), bakra(II) i cinka(II) s karnozinom te s karnozinom i jednom od odabranih organskih
kiselina (sukcinska, adipinska, pimelinska). U tu svrhu proveden je niz otopinskih,
solvotermalnih i mehanokemijskih sintetskih reakcija. Dobiveni produkti analizirani su
difrakcijom rentgenskog zraĉenja na polikristalnom uzorku i infracrvenom spektroskopijom.
Za dva spoja za koje su prireĊeni kvalitetni jediniĉni kristali odreĊena je kristalna i
molekulska struktura metodom difrakcije rentgenskog zraĉenja na jediniĉnom kristalu ĉime je
utvrĊeno da je nastao spoj [Cu2(C9H12N4O3)2(H2O)2]·H2O, koji ima dinuklearnu strukturu dok
spoj [Zn(C7H10O4)]n ima strukturu polimerne trodimenzijske mreže.

Abstract (english)

Within this thesis, the possibility of the formation of coordination compounds of nickel(II),
copper(II) and zinc(II) with carnosine and with carnosine and one of the selected organic
acids (succinic, adipic, pimelic) was investigated. For this purpose, a series of solution,
solvothermal and mechanochemical sintetic reactions were performed. The obtained products
were analyzed by powder X-ray diffraction and infrared spectroscopy. For two compounds
single crystals were prepared and the crystal and molecular structure was determined by X-ray
diffraction. It was found that the compound [Cu2(C9H12N4O3)2(H2O)2]·H2O has a dinuclear
structure while compound [Zn(C7H10O4)]n forms a polymeric three-dimensional network.
