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)

摘要

The structure of a binuclear cadmium(II) quaternary complex, [Cd2(phen)2- Q2(BP)]n 1 (phen = 1,10-phenanthroline, BP = biphenyl-4,4--dicarboxylic acid, Q = 8-hydroxy- quinoline-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 P21 with a = 13.1906(18), b = 10.9623(15), c = 16.947(2) -, β = 111.3430(10)°, V = 2282.5(5) -3, Z = 4, Mr = 556.85, Dc = 1.620 g/cm3, F(000) = 1116, μ = 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 π-π stacking interactions a supramolecular structure is formed in 1.
