Abstract

The synthesis and X- ray crystal structure of RuCl2 [(Ph)2 PC2 H4 P(Ph)C2 H4 P(Ph)2] are reported. The crystals are monoclinic, space group P2I/c with cell dimensions a = 10.389 (2) A, b = 27.815 (5) A, c = 14.377 (3) A, β = 109.17 (1)º. The structure was solved by direct method; least-squares refinement converged to a final conventional R = 5.551% for 3692 independent observed reflections collected by counter methods. The structure consists of discrete monomeric molecules. The central metal atom is octahedrally coordinated with the four phosphorus atoms of the ligand in the equatorial plane and with the two chlorine atoms atoms in the axial positions. The PH2P - Ru and PhP - Ru pairs

have an average distance of 2.392 A and 2.295 A, respectively.
