X-ray powder diffraction data for Dichloro [bis(2-diphenylphosphinoethyl) phenylphosphine] [dimethylsulfoxide] Ruthenium (II) is reported. The powder pattern was obtained using CuKα radiation. The lattice parameters determinated by least-squares refinement for the monoclinic space group P21/c are: a = 21.073(3) Å, b = 11.970(2) Å, c = 16.889(3) Å, and β = 107.72(1)°, with M20 = 10.67 and F30 = 15.4 (0.0145, 134), and are in good agreement with those obtained from the single crystal structure determination. Observed and calculated X-ray powder diffraction data are given for the titled compound.
