Crystal structure and characterization of a binuclear Cd(II) quaternary coordination complex [Cd2(phen)2Q2(BP)]n (phen=1,10-phenanthroline, BP = biphenyl-4,4′-dicarboxylic acid, Q=8-hydroxyquinoline anion)

The structure of a binuclear cadmium(H) quaternary complex, [Cd-2(phen)(2)-Q(2)(BP)](n) 1 (phen = 1,10-phenanthroline, BP = biphenyl-4,4'-dicarboxylic acid, Q = 8-hydroxyquinoline-anion), has been determined by X-ray crystallography and characterized by elemental analysis, IR spectrum and thermogravimetric analysis. It crystallizes in the monoclinic system, space group P2(1)/n with a = 13.1906(18), b = 10.9623(15), c = 16.947(2) angstrom, beta = 111.3430(10)degrees, V = 2282.5(5) angstrom(3), Z = 4, M-r = 556.85, D-c = 1.620 g/cm(3), F(000) = 1116, mu = 0.994 mm(-1) and S = 1.056. In the structure, 1D chains are connected via biphenyl-4,4'-dicarboxylic acid, 8-hydroxy quinoline anion and binuclear cadmium atoms into an infinite 1-D molecular chain architecture. Via aryl ring pi-pi stacking interactions a supramolecular structure is formed in 1.
