Abstract
U ovom diplomskom radu ispitana je mogućnost kokristalizacije koordinacijskih spojeva vrste CoX2L (gdje je X = Cl, Br ili I, a L = 6,6'-dimetil-2,2'-bipiridin) i perhalogeniranih donora halogenske veze, s ciljem izučavanja mogućnosti nastajanja kokristala s metaloorganskom podjedinicom te uspoređivanja akceptorskog potencijala halogenidnih iona koordiniranih na metalni centar za ostvarivanje halogenske veze. Mehanokemijskom sintezom i kristalizacijom iz otopine priređeno je sedam novih kokristala koji su okarakterizirani difrakcijom rendgenskoga zračenja na praškastom uzorku, difrakcijom rendgenskoga zračenja u jediničnom kristalu i termogravimetrijskom analizom. U svim strukturno okarakteriziranim kokristalima utvrđeno je kako je halogenska veza Co−X···I (X = Cl, Br ili I) dominantna međumolekulska interakcija koja se ostvaruje između atoma joda perhalogeniranog spoja kao donora halogenske veze i halogenidnog liganda koordinacijskog spoja kobalta(II) kao akceptora halogenske veze. Pokazano je i da se korištenjem perhalogeniranih donora različite topičnosti i geometrije može ugađati supramolekulska arhitektura i termička stabilnost dobivenih produkata.
Abstract (english)
Within this master thesis, the possibility of cocrystallization of coordination compound CoX2L (X = Cl, Br or I, L = 6,6'-dimethyl-2,2'-bipyridine) and perhalogenated halogen bond donors was examined, with the aim of studying the plausibility of cocrystal formation with a metalorganic subunit and comparing the ability of the halide ions coordinated to the Co(II) metal center to act as a halogen bond acceptor. Seven new cocrystals were synthesized by mechanochemical synthesis and crystallization from solution. The obtained products were characterized by powder and single crystal X-ray diffraction, and by thermogravimetric analysis. Structural analysis of the cocrystals revealed that the dominant supramolecular interactions are Co−X···I halogen bonds (X = Cl, Br or I) formed between the iodine atom of the halogen bond donor and the halogen ligand of the cobalt(II) coordination compound as a halogen bond acceptor. The results of this study also demonstrate the possibility of altering supramolecular architectures and thermal stabilities of the products by utilizing donors featuring different geometries and topicities.
