Abstract
Većina danas poznatih kristala je nesavitljiva, no neki molekulski kristali ipak pokazuju svojstvo savitljivosti. Po uzoru na njih sintetizirani su koordinacijski polimerni spojevi [CuCl2(3-NO2py)2]n (1) i [CuBr2(3-NO2py)2]n (2) iz odgovarajućih bakrovih(II) halogenida i 3-nitropiridina otopinskom sintezom i metodom tekućinske difuzije uz variranje otapala: metanola, etanola, izopropanola i acetona. Priređeni spojevi su okarakterizirani infracrvenom spektroskopijom, metodama termičke analize i difrakcijom rendgenskog zračenja u polikristalnom uzorku, te im je određena je molekulska i kristalna struktura difrakcijom rendgenskog zračenja u monokristalnom uzorku. Ispitan je odziv igličastih monokristala na primjenu vanjske mehaničke sile te je ustanovljeno da se kristali spoja 1 i 2 mogu elastično saviti po dva različita para nasuprotnih ploha koji se pružaju u smjeru izduženosti kristala. Elastičan odziv kristala oba spoja je kvantificiran. Uspoređene su međumolekulske interakcije te je ustanovljeno da jače međumolekulske interakcije kao i njihova tendencija izotropiji u smjerovima ortogonalnim na smjer izduženja kristala pogoduju elastičnoj fleksibilnosti istraženih spojeva.
Abstract (english)
The majority of crystals known today are inflexible but some cases show otherwise. Having in mind the structural characteristics of those crystals, coordination polymers of [CuCl2(3-NO2py)2]n (1) and [CuBr2(3-NO2py)2]n (2) were synthesized via solvent-layering using different solvents: methanol, ethanol, isopropanol, and acetone. Molecular and crystal structures of compounds 1 and 2 were determined by singlecrystal X-ray diffraction analysis. The compounds were further analyzed using infrared spectroscopy, thermal methods, and powder X-ray diffraction. Acicular singlecrystals of both compounds were subjected to mechanical force upon which they gave different elastic responses. Compound 1 and 2 crystals have two-dimensional flexibility that differs. The elasticity of both flexible crystals was quantified. Intermolecular interactions, which are an important feature when it comes to elastic crystals, were compared between both crystal structures. The observed difference in hydrogen bonding is potentially the reason behind the different elastic properties of the crystals of 1 and 2.
