Abstract
U ovom diplomskom radu sintetizirana su tri koordinacijska spoja kobalta(II) korištena kao akceptori halogenske veze – dikloro-, dibromo- i dijodo-(6,6´´-dibrom-2,2´:6´,2´´- terpiridin)kobalt(II). Koordinacijski spojevi kokristalizirani su s odabranim perfluoriranim jodbenzenskim spojevima kao donorima halogenske veze s ciljem usporedbe potencijala halogenog liganda kao akceptora halogenske veze Co–X∙∙∙I (X = Cl, Br, I) kao i izučavanja utjecaja bromovih atoma na periferiji terpiridinskog liganda na ostvarivanje halogenskih veza, kao i njihov akceptorski potencijal. Sinteza koordinacijskih spojeva i kokristala provedena je mehanokemijski, dok su jedinični kristali dobiveni kristalizacijom iz otopine. Mehanokemijskom sintezom ukupno je dobiveno osam novih kristalnih produkata koji su okarakterizirani difrakcijom rendgenskog zračenja na praškastom uzorku. Za one produkte čiji su jedinični kristali uspješno priređeni dodatno su okarakterizirani difrakcijom rendgenskog zračenja u jediničnom kristalu i termogravimetrijskom analizom. Strukturnom analizom kokristala utvrđeno je kako je dominantna međumolekulska interakcija Co–X∙∙∙I (X = Cl, Br, I). Atomi broma na periferiji liganda sudjeluju u kontaktima Br∙∙∙H, dok samo u jednom kokristalu ostvaruju halogenske veze Co–Br∙∙∙Br i Br∙∙∙I u kojima sudjeluju kao donori i kao akceptori.
Abstract (english)
In this diploma thesis three cobalt(II) coordination compounds were synthesized and used as halogen bond acceptors – dichloro-, dibromo-, and diiodo-(6,6"-dibromo-2,2':6',2'- terpyridine)cobalt(II). Coordination compounds were cocrystallized with selected perfluorinated iodobenzene compounds as halogen bond donors in order to compare the potential for halogen bonding of the halogen atoms located peripherally on the terpyridine ligands, as well as their acceptor potential. Mechanochemical methods were used to synthesize bulk coordination compounds and cocrystals, whereas crystallization from solution was used to obtain single crystals. Mechanochemical synthesis resulted in eight new crystalline phases which were then identified using X-ray powder diffraction. The products were also characterized by thermogravimetric analysis and single crystal X-ray diffraction in cases where single crystals were successfully obtained. Structural analysis of the compounds revealed that the dominant intermolecular interaction is Co–X∙∙∙I (X = halogen). The bromine atoms on the ligand's periphery participate in Br∙∙∙H contacts, but in one cocrystal they participate in the halogen bonds Co–Br∙∙∙Br and Br∙∙∙I, where they act as both acceptors and donors.
