Özet
A mixed-ligand orotato (HOr) complex of Cu(II) with 2,2'-bipyridine (bipy) was synthesized and characterized by elemental analysis, magnetic susceptibility, UV-vis and FT-IR spectroscopy, TG / DTA techniques and X-ray diffraction analysis. X-Ray diffraction analysis has shown that the square-pyramidal five-coordinate copper atom is chelated by the deprotonated N3 pyrimidine atom and the carboxylate oxygen atom of the bidentate orotato dianion, and to the two nitrogen atoms of the 2,2'-bipyridine molecule. A water molecule is attached above the N3O plane. Thermal analyses showed that the title compound decomposes in two steps over the range 20 - 1000 degrees C on heating in a static air atmosphere. Intermolecular hydrogen-bonds and pi-ring interactions lead to the formation of a three-dimensional network.
