Tetra-chlorido[(diphenyl-phosphino)diphenyl-phosphine oxide-?O]zirconium(IV) benzene monosolvate.

ABSTRACT: In the title centrosymmetric mononuclear Zr(IV) compound, [ZrCl(4){P(O)(C(6)H(5))(2)P(C(6)H(5))(2)}(2)]·C(6)H(6), the central Zr(IV) ion is coordinated by two O atoms from two symmetry-related (diphenyl-phosphino)diphenyl-phosphine ligands and four Cl atoms in a distorted octahedral geometry with the four Cl atoms in the equatorial positions. The mol-ecule lies about a center of inversion and the benzene solvent mol-ecule about another center of inversion. The P=O bond [1.528?(2)?Å] is slightly longer than a typical P=O double bond (average 1.500?).
