摘要
The structure of [COCl2(C6H4N3CH2Ph)(2)] has been determined by X-ray crystallography. It is also characterized by elemental analysis, IR and electronic spectroscopy, and by thermogravimetric differential thermal analysis. It crystallizes in the monoclinic system, space group C2/c, with lattice parameters a = 16.133(3) angstrom, b = 11.355(2) angstrom, c = 15.637(3) angstrom, beta = 117.22(3)degrees, and Z= 8. The crystal structure of the title compound consists of monomeric molecules of [COCl2(C6H4N3CH2Ph)(2)] with slightly distorted tetrahedron geometry for the CoCl2N2 chromophore. The thermal gravimetry (TG) data indicate that there are four decomposition steps with five endothermic peaks. The final product of the thermal decomposition is CoCl2. Elemental analysis and the electronic and IR spectra are in agreement with the structural data.
