Abstract

Istražen je utjecaj boˇcnog ogranka aminokiselina na topologiju koordinacijskih polimera bakra(II) s aminokiselinama i 4,4’-bipiridinom. U provedbi eksperimenata korištene su sve proteinogene aminokiseline. Priređeno je i strukturno karakterizirano dvadeset različitih koordinacijskih polimera, jedan koordinacijski polimer s glicilglicinom i jedan diskretni kompleksni spoj s histidinom, te tri vrste koordinacijskih polimera koji sadrže samo bakrove(II) i nitratne ione, te 4,4’-bipiridin kao premošćujući ligand. Osim utjecaja strukture bočnog ogranka, prouˇcen je i utjecaj otapala na dimenzionalnost i topologiju priređenih spojeva. Svi spojevi su strukturno karakterizirani difrakcijom rentgenskog zračenja na jediničnom kristalu, difrakcijom rentgenskog zračenja na polikristalnom uzorku, termogravimetrijskom analizom te infracrvenom spektroskopijom uz prigušenu totalnu refleksiju.

Abstract (english)

The influence of the amino-acids side-chain on the topology of coordination polymers of copper(II) with selected amino-acids and 4,4’-bipyridine was investigated. All proteinogenic amino-acids were used in the experiments. Twenty different coordination polymers, one coordination polymer with glycylglycine and one discrete complex complex with histidine, and three types of coordination polymers containing only copper(II) and nitrate ions, and 4,4’-bipyridine as a bridging ligand were prepared and structurally characterized. In addition to the influence of the side-chain structure, solvent impact on the dimensionality and topology of the target compounds was also studied, as well as the counterion influence. The compounds were structurally characterized by single crystal X-ray diffraction and X-ray diffraction on a polycrystalline sample, thermogravimetric analysis, and attenuated total reflectance spectroscopy.
