trans-Acetyl-dicarbon-yl(η(5)-cyclo-penta-dien-yl)[tris-(furan-2-yl)phosphane-κP]molybdenum(II)

The title compound, [Mo(C5H5)(C2H3O)(C12H9O3P)(CO)2], was prepared by reaction of [Mo(C5H5)(CO)3(CH3)] with tris-(furan-2-yl)phosphane. The Mo(II) atom exhibits a four-legged piano-stool coordination geometry with the acetyl and phosphine ligands trans to each other. The O atom of the acetyl ligand points down, away from the Cp ring. In the crystal, mol-ecules form centrosymmetrical dimers via π-π inter-actions between furyl rings [the centroid-centroid distance is 3.396 (4) Å]. The dimers are linked by C-H⋯O hydrogen bonds into layers parallel to (100).
