The structure and bonding of [Ru(DMSO-S)3(DMSO-O)Cl2] , has been studied by means of single-crystal X-ray diffraction .X-ray crystallography shows a monoclinic unit cell , space group P21/n , with z = 4, a = 9.09(2) Å, b = 18.166(3)Å, c = 11.483(2) Å,V = 1895.9(6) Å3 at 293(2) K .Crystallographic results are consistent with a regular structure of the complex in which the ruthenium(II) is surrounded by three sulfur and one oxygen atoms from four dimethyl sulfoxide molecules and two chloride ions.
