Abstract
U okviru ovog diplomskog rada sintetizirani su koordinacijski polimeri bakrovih(II) klorida (1) i bakrovih(II) bromida (2) s 3-metilpiridinom (3-Mepy, a) i 4-metilpiridinom (4-Mepy, b). Priređeni spojevi [CuCl2(3-Mepy)2]n (1a), [CuCl2(4-Mepy)2]n (1b), [CuBr2(3-Mepy)2]n (2a) i [CuBr2(4-Mepy)2]n (2b) sintetizirani su i kristalizirani metodom tekućinske difuzije uz primjenu različitih otapala, metanola, etanola i izopropanola. Nastali produkti okarakterizirani su infracrvenom spektroskopijom (IR), termičkim metodama (TG/DSC) i metodom difrakcije rendgenskih zraka u polikristalnom uzorku (PXRD), dok su metodom difrakcije rendgenskog zračenja u monokristalnom uzorku (SCXRD) određene njihove molekulske i kristalne strukture. Ispitan je odziv igličastih kristala priređenih spojeva na primjenu vanjske mehaničke sile, te je uočeno da su kristali spojeva 1a, 2a i 2b plastični, a kristali spoja 1b elastični te je njihov mehanički odziv kvantificiran. Pokazalo se da male razlike u geometriji te posljedično i jakosti vodikovih veza ostvarenih u kristalnim strukturama priređenih spojeva imaju značajan utjecaj na vrstu mehaničkog odziva njihovih jediničnih kristala.
Abstract (english)
This master thesis presents syntheses of coordination polymers of copper(II) chloride (1) and copper(II) bromide (2) with 3-methylpyridine (3-Mepy, a) and 4-methylpyridine (4-Mepy, b). Complexes [CuCl2(3-Mepy)2]n (1a), [CuCl2(4-Mepy)2]n (1b), [CuBr2(3-Mepy)2]n (2a) and [CuBr2(4-Mepy)2]n (2b) were synthesized and crystallized via the layering technique using different solvents, methanol, ethanol, and isopropanol. The resulting compounds were characterized by infrared spectroscopy (IR), thermal methods (TG/DCS), and powder X-ray diffraction (PXRD), while the single-crystal X-ray diffraction (SCXRD) method was used to determine their molecular and crystal structures. Crystals of all prepared complexes were subjected to the application of mechanical force and their responses were mapped out. Crystals of 1a, 2a, and 2b were plastically deformable, while crystals of 1b were elastically responsive and their responses were quantified. It was observed that slight differences in the geometry and consequently the strength of the hydrogen bonds that materialized in the crystal structures of prepared compounds have a substantial impact on the type of mechanical responses.
