Deskripsi

The structure of a new binuclear cadmium (II) complex, [Cd(H2O)2(Sal)2]2 (Sal= salicylate), has been determined by X-ray crystallography. It was also characterized byelemental analysis, its IR spectrum and thermogravimetric-differential scanningcalorimetry (TG-DSC). It crystallizes in the monoclinic system, space group P21/c, withlattice parameters a = 15.742(3) å, b = 12.451(3) å, c = 7.7225(15) å, β = 96.07(3)o andZ = 4. Two cadmium (II) ions are bridged by two μ2-carboxy oxygen atoms. Eachcadmium atom lies in a distorted capped octahedron coordination geometry. The thermalgravimetry (TG) data indicate that there are four discrete decomposition steps with twoendothermic peaks and one exothermic peak. The final thermal decomposition product isCdO.
