Abstract
U okviru ovog rada sintetizirani su koordinacijski polimeri kadmijevih(II) halogenida s nitrilnim derivatima piridina kao ligandima. Priređeno je 6 kompleksnih spojeva ([CdCl2(3-CNpy)2]n (A1), [CdBr2(3-CNpy)2]n (A2), [CdI2(3-CNpy)2]n (A3), [CdCl2(4-CNpy)2]n (B1), [CdBr2(4-CNpy)2]n (B2) i [CdI2(4-CNpy)2]n (B3)) klasičnom otopinskom sintezom. Priređeni spojevi analizirani su infracrvenom spektroskopijom, metodama termičke analize te difrakcijom rendgenskog zračenja u praškastom uzorku, te im je određena molekulska i kristalna struktura rendgenskom strukturnom analizom metodom difrakcije rendgenskog zračenja u monokristalnom uzorku. U kristalnom pakiranju ustanovljena je važnost supramolekulskih interakcija, prvenstveno vodikovih veza ali i dipol-dipol interakcija, kod povezivanja polimernih lanaca u kristalnu strukturu. Također, ispitan je odziv igličastih kristala na primjenu vanjske mehaničke sile čime je ustanovljen njihov elastičan odziv u slučaju spojeva A1, A2 i B1 te plastičan u slučaju B2, dok su se kristali spojeva A3 i B3 pokazali nefleksibilnima. Opaženi mehanički odzivi korelirani su s jakosti i usmjerenosti ostvarenih supramolekulskih interakcija u kristalnom pakiranju priređenih spojeva.
Abstract (english)
This diploma thesis presents synthesis of coordination polymers of cadmium(II) halides with 3-cyanopiridine and 4-cyanopiridine. Six compounds ([CdCl2(3-CNpy)2]n (A1), [CdBr2(3-CNpy)2]n (A2), [CdI2(3-CNpy)2]n (A3), [CdCl2(4-CNpy)2]n (B1), [CdBr2(4-CNpy)2]n (B2) and [CdI2(4-CNpy)2]n) (B3) were prepared by classical solution synthesis. The products were characterized by infrared spectroscopy, thermal methods and powder X-ray diffraction, while molecular and crystal structure were determined by single crystal X-ray diffraction analysis. The importance of supramolecular interactions (particularly hydrogen bonds and dipole-dipole interactions) in linking polymeric building units into the supramolecular architecture is established. Also, the response of needle-like crystals to the application of external mechanical force was investigated, and elastic (A1, A2, B1) and plastic (B2) flexibility was established. Furthermore, crystals of two compounds (A3 and B3) showed to be stiff and brittle. The observed mechanical responses were correlated with the strength and geometry of supramolecular interactions in the crystal packings of prepared products.
