Synthesis and structure of halogen bonded cocrystals of an o-hydroxy imine

U sklopu ovog diplomskog rada pripravljen je imin kondezacijom o-vanilina i 4-aminobenzonitrila. Mehanokemijskom sintezom, sintezom iz otopine i metodom ubrzanog starenja izučavana je mogućnost nastajanja kokristala molekule imina s odabranim donorima halogenske veze: 1,2- i 1,4-dijodtetrafluorbenzenom. Pripravljeni kokristali izučavani su metodom difrakcije rentgenskih zraka na praškastom uzorku, termogravimetrijom i razlikovno-pretražnom kalorimetrijom. Za oba pripravljena kokristala metodom difrakcije rentgenskog zračenja na jediničnom kristalu iznađena je molekulska i kristalna struktura, te je ista dovedena u vezu s njihovim termičkim svojstvima.Within this master thesis an imine was prepared through condensation of o-vanillin and 4-aminobenzonitrile. The possibility of cocrystallization of the selected imine and two halogen bond donors (1,2- and 1,4-diiodotetrafluorobenzene) was investigated by means of mechanochemical synthesis, solution based synthesis and accelerated ageing. The cocrystals were described by powder X-ray diffraction, thermogravimetry and differential scanning calorimetry. The crystal and molecular structures of two prepared compounds were explored by single crystal X-ray diffraction, and correlated with thermal properties
