STRUCTURAL CHARACTERIZATION OF A CADMIUM(II)-SULFATO COMPLEX, [Cd(N,N '-DIETHYL THIOUREA)(4)(SO4)]

A cadmium(II) complex, tetrakis(N,N'-diethylthiourea)sulfatocadmium(II), [Cd(Detu)(4)SO4] (1) is prepared and its crystal structure is determined by X-ray crystallography. The crystal structure of the complex consists of an independent molecule with the central cadmium atom coordinated to four thione sulfur atoms of Detu and two oxygen atoms of the sulfate ligand. The Cd atom has a pseudo-octahedral coordination environment with the cis angles varying from 57.68 degrees to 126.57 degrees, while the trans angles fall in the range of 142 degrees to 169 degrees. The new complex was also characterized by IR and NMR spectroscopy and the spectroscopic data are discussed in terms of the nature of bonding.
