SYNTHESIS, CRYSTAL STRUCTURE, SPECTRAL AND MAGNETIC PROPERTIES OF MONONUCLEAR COPPER(II) COMPLEX WITH PYRAZINE-MODULATED 2,2'-DIPYRIDYLAMINE
New copper(II) complex [Cu(Hppza)(CH3COO)2]·2H2O was synthesized via the interaction of Cu(CH3COO)2∙H2O with the unsymmetrical pyrazine-modulated dipyridylamine ligand – Hppza. The crystal structure, spectral and magne-tic properties of this complex are determined. It was found that the coordination polyhedron of the copper(II) ion in this complex is an elongated octahedron, in the equatorial plane of which there are two nitrogen atoms from Hppza ligand and two oxygen atoms from two carboxylate anions. The formation of intermolecular hydrogen bonds has been observed.
