The title compound, [Mo(C5H5)(C2H3O)(C13H13P)(CO)2], was prepared by reaction of [Mo(CH3)(C5H5)(CO)3] with methyldiphenylphosphane. The MoII atom exhibits a fourlegged piano-stool coordination geometry with the acetyl and phosphane ligands trans to each other. There are several intermolecular C—HO hydrogen-bonding interactions involving carbonyl and acetyl O atoms as acceptors. A close nearly parallel – interaction between the cyclopentadienyl plane and the phenyl ring of the phosphane ligand is present, with an angle of 6.4 (1) between the two least-squares planes. The centroid-to-centroid distance between these groups is 3.772 (3) A˚ , and the closest distance between two atoms of these groups is 3.449 (4) A˚ . Since each Mo complex is engaged in two of these interactions, the complexes form an infinite - stack coincident with the a axis.
