Synthesis and crystal structure of bridging binuclear complex [Co(DPC)2Co(H2O)5]•2H2O

The new complex formulated [Co(DPC)(2)]-Co(H2O)(5)] (.) 2H(2)O (HDPC- is pyridine-2,6-dicarboxylate) has been synthesized and the crystal structure was determined by X-ray diffraction. The crystal structure of the complex belongs to monoclinic system with space group P2(1)/c, a=0.83850(10) nm, b=2.7386(4) nm, c=0.9610(2) nm, beta= 98.280 (10) degrees, V=2.1838(6) nm(3), Z=4, D-c= 1.746 g(.)cm(-3), mu=1.597 mm(-1). In the crystal the two Co2+ are in distorted octahedrons. The part of [Co(DPC)2] possess an approximate D-2d symmetry, while the part of [OCo(2)(OH2)(5)] has an approximate C2 symmetry.
