Abstract
U sklopu ovog diplomskog rada pripravljene su soli 3-halogenpiridina: 3-klorpiridinijev klorid, 3-klorpiridinijev bromid, 3-brompiridinijev klorid i 3-brompiridinijev bromid. Mehanokemijskom sintezom i kristalizacijom iz otopine izučavana je mogućnost nastajanja kokristala pripravljenih soli s odabranim perhalogeniranim donorima halogenske veze: 1,4- dibromtetrafluorbenzenom, tetrafluor-1,4-dijodbenzenom, tetrafluor-1,3-dijodbenzenom, tetrafluor-1,2-dijodbenzenom i trifluor-1,3,5-trijodbenzenom. Pripravljeni spojevi izučavani su metodom difrakcije rentgenskih zraka na praškastom uzorku i razlikovnom pretražnom kalorimetrijom. Za četiri pripravljena kokristala je metodom rentgenske difrakcije na jediničnom kristalu iznađena molekulska i kristalna struktura. Proučavanjem struktura ustvrđene su geometrijske značajke ostvarenih interakcija te je izučen akceptorski potencijal halogenidnih iona i donorski potencijal halogenih atoma supstituiranih na 3-halogenpiridinijevom kationu.
Abstract (english)
As part of this master thesis, the following 3-halogenpyridinium salts were prepared: 3-chloropyridinium chloride, 3-chloropyridinium bromide, 3-bromopyridinium chloride and 3-chloropyridinium bromide. Mechanochemical synthesis and crystallization from solution were used to study the cocrystallization of 3-halogenpyridinium salts with five halogen bond donors: 1,4-dibromotetrafluorobenzene, 1,4-diiodotetrafluorobenzene, 1,3- diiodotetrafluorobenzene, 1,2-diiodotetrafluorobenzene and 1,3,5-triiodo-2,4,6- trifluorobenzene. The crystals were analyzed by powder X-ray diffraction and differential scanning calorimetry. Crystal and molecular structures of four prepared cocrystals derived from 3- halogenpyridinium salts and the above-mentioned halogen bond donors were determined by single crystal X-ray diffraction. Crystal structures of these four cocrystals were analyzed in terms of their geometrical features while studying halogen-bonding potential of the halide ions, as well as the potential of halogen atoms substituted on the 3-halogenpyridinium cation to act as halogen bond donors.
