Tetrachlorido[(diphenylphosphino)diphenylphosphine oxide-κO]zirconium(IV) benzene monosolvate

Abstract

In the title centrosymmetric mononuclear ZrIV compound, [ZrCl4{P(O)(C6H5)2P(C6H5)2}2]·C6H6, the central ZrIV ion is coordinated by two O atoms from two symmetry-related (diphenylphosphino)diphenylphosphine ligands and four Cl atoms in a distorted octahedral geometry with the four Cl atoms in the equatorial positions. The molecule lies about a center of inversion and the benzene solvent molecule 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 ).
