Hydrothermal Synthesis,Crystal Structure and Thermal Stability Properties of the Complex [Cd_2(phen)_2(C_(14)H_(11)O_3)_4(CH_3CH_2OH)]·(CH_3OH)·(H_2O)

A dinuclear cadmium complex [Cd2(phen)2(C14H11O3)4(CH3CH2OH)]·(CH3OH)·(H2O) has been synthesized with benzilic acid and 1,10-phenanthroline by hydrothermal method.The crystal structure was determined by X-ray diffraction with crystal parameters as follows:triclinic system with space group P1,a = 1.21298(10),b = 1.32586(11),c = 2.4815(2) nm,α = 76.2630(10),β = 81.4500(10),γ = 69.1700(10)o,V = 3.6143(5) nm3,Dc = 1.438 g/cm3,Z = 1,F(000) = 1600,the final GOOF = 0.937,R = 0.0521 and wR = 0.1328.In the title complex,the dinuclear structure is defined by carboxyl oxygen atoms adopting a monodentate bridged coordination mode.The coordination environment of Cd(Ⅱ) ion is CdO4N2,giving a distorted octahedral coordination geometry.TG analysis shows that the title complex is stable under 140 ℃.
