Abstract

U okviru ovog diplomskog rada istražena je mogućnost nastajanja koordinacijskih spojeva
cinka(II) s derivatima imidazola i halogenidima te s imidazolom i jednom od odabranih
organskih kiselina (sukcinska, adipinska, pimelinska). U tu svrhu proveden je niz otopinskih i
mehanokemijskih sintetskih reakcija. Dobiveni produkti, [ZnX2(1-Meim)2] (1-Meim = 1-
metilimidazol; X = Cl, Br (1a,b)); [ZnX2(2-Et-4-Meim)2] (2-Et-4-Meim = 2-etil-4-
metilimidazol; X = Cl, Br, I (2a-c)); dva polimorfa [ZnBr2(1-Meim)]n (3a i b); spoj cinka(II) s
imidazolom (im) i sukcinskom (4a), adipinskom (4b) i pimelinskom (H2pim), [Zn(im)2(pim)]n
(4c) analizirani su difrakcijom rendgenskog zračenja na polikristalnom uzorku i infracrvenom
spektroskopijom. Za četiri spoja su priređeni kvalitetni jedinični kristali i određena je kristalna
i molekulska struktura metodom difrakcije rendgenskog zračenja na jediničnom kristalu.
Mehanokemijskom sintezom priređen je 2a, dok su otopinskom sintezom dobiveni 3a, 3b i 4c.

Abstract (english)

Within this thesis, the possibility of the formation of coordination compounds of zinc(II) with
imidazole derivatives and halide ions, and with imidazole and one of the selected organic acids
(succinic, adipic, pimelic) was investigated. For this purpose, a series of solution and
mechanochemical reactions were performed. The obtained products, [ZnX2(1-Meim)2] (1-
Meim = 1- methylimidazole; X = Cl, Br (1a,b)); [ZnX2(2-Et-4-Meim)2] (2-Et-4-Meim = 2-
ethyl-4-methylimidazole; X = Cl, Br, I (2a-c)); two polymorphs of [ZnBr2(1-Meim)]n (3a, b);
complex of zinc(II) with imidazole (im) and succinic (4a), adipic (4b) and pimelic acid
(H2pim), [Zn(im)2(pim)]n (4c), were analyzed by powder X-ray diffraction and infrared
spectroscopy. For four compounds single crystals were prepared and the crystal and molecular
structure was determined by X-ray diffraction. 2a was synthesized by the mechanochemical
method while 3a, 3b and 4c were obtained by solution synthesis.
