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°C on heating in a static air atmosphere. Intermolecular hydrogen-bonds and π-ring interactions lead to the formation of a three-dimensional network. © 2005 Verlag der Zeitschrift für Naturforschung.
