Tetrakis(-4-chlorophenoxyacetato-²O,O')dimolybdenum(II)

T. Liwporncharoenvong and R. L. Luck

Abstract: The crystal structure determination of the title compound, [Mo₂(C₈H₆ClO₃)₄], confirms the existence of a quadruple bond between the Mo atoms, with an Mo-Mo distance of 2.101 (5) Å. One half of the molecule constitutes the asymmetric unit and the carboxylate ligands define a paddle-wheel 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.
