The crystal structure of cis-dichloro[1,4-bis(diphenylphosphino)butane](ethylenediamine)ruthenium, cis- [RuCl 2 (dppb)en] has been synthesized and determined by X-ray diffraction. This compound found to crystallize with two dichloromethane solvent molecules in a Triclinic system, space group P-1, with the following cell parameters: a =10.338(6) Å, b = 13.024(5) Å, c = 14.491(5) Å, a = 81.017(16) ( 87.650(3) ( o ), γ =66.950(3) ( o ). V = 1773.0(13) Å3,Z = 2 and D calc = 1.552 mg/m 3 The crystal structure was solved by Patterson method and refined on F2 by full-matrix least squares to final value R = 0.0282 and wR = 0.0720 with 9430 reflections. The Ru(II) ion is octahedrally coordinated to one of dppb and en ligands as well as two chloride ions in full cis-configuration form.
