Tetrakis(μ-4-chlorophenoxyacetato-κ²<i>O</i>,<i>O</i>′)dimolybdenum(II)

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.
