Synthesis, characterization and crystal structure of copper(II) complex of succinate and 2,2′-bipyridyl

The mixed ligand copper(II) complex of succinate and 2,2′-bipyridyl was synthesized from disodium succinate, 2,2′-bipyridine and copper nitrate. The structure of the synthesized complex was determined by micro-analysis, IR, thermogravimetric analysis and X-ray crystallography. The thermal decomposition of the complex under an inert atmosphere has been studied. The crystal structure is monoclinic space group P21/n with parameters a = 15.080(9) Å, b = 22.406(13) Å, c = 15.138(9) Å, β = 91.539°, V = 5113(5) Å3, Z = 4, 1.534 Mg/m3, R = 0.0911 and Mr = 1181.08. The geometry around copper atom is distorted octahedral. The complex consists of a dimer in which each Cu atom is linked through two carboxylate-oxygen atoms from a tetradentate succinate ligand and four nitrogen atoms from two chelating 2,2′-bipyridyl groups. The succinate ligand bridges between the two Cu atoms. © 2010 Elsevier B.V.
