A synthetic study in the Cd-Se-O-Cl system led to formation of the new oxochloride compound Cd-4(SeO3)(2)OCl2 via solid state reactions. The compound crystallizes in the orthorhombic space group Fmmm with cell parameters a = 7.3610(3) angstrom, b = 15.4936(2) angstrom, c = 17.5603(3) angstrom, Z = 8, S = 0.969, F(000) = 2800, R = 0.0185, R-w = 0.0384. Single crystal X-ray data were collected at 293 K. The crystal structure can be considered as layered and the building units are distorted [Cd(1)O-6] octahedra, distorted [Cd(2)O-8] cubes, irregular [Cd(3)O4Cl2] polyhedra and SeO3E trigonal pyramids. There are two crystallographically unique Cl atoms that both are half occupied. Thermogravimetric studies show that the compound starts to decompose at 500 degrees C. The crystal structure of the new compound is closely related to the previously described compound Cd-4(SeO3)(2)Cl-4(H2O).
