Tetrakis(μ-4-chlorophenoxyacetato-κ2O,O′) -dimolybdenum(II)

Abstract

The crystal structure determination of the title compound, [Mo 2(C8H6ClO3)4], confirms the existence of a quadruple bond between the Mo atoms, with an Mo-Mo distance of 2.101 (5) ̊. One half of the molecule constitutes the asymmetric unit and the carboxylate ligands define a paddlewheel structure, with similar O-C-O angles of 122.9 (3) and 123.7 (3)°. The interplanar angles between the acetate and 4-chlorophenoxy planes in the two independent ligands are 135.9(8) and 91.3(8)°, which is indicative of a dramatic difference in the orientation of the ligands. © 2005 International Union of Crystallography Printed in Great Britain - all rights reserved.
