چکیده

The title compounds, [Mo(C5H5)(COCH3)P(CH3)2(C6H5)(CO)2], (1), and [Mo(C5H5)(COCH3)P(C2H5)(C6H5)2)(CO)2], (2), have been prepared by phosphine-induced migratory insertion from [Mo(C5H5)(CO)3(CH3)]. Both complex mol-ecules exhibit a four-legged piano-stool geometry with trans-disposed carbonyl ligands along with Mo-P bond lengths and C-Mo-P angles that reflect the relative steric pressure of the respective phosphine ligand. The structure of compound (1) exhibits a layered arrangement parallel to (100). Within the layers mol-ecules are linked into chains along [001] by non-classical C-H⋯O inter-actions between the acetyl ligand of one mol-ecule and the phenyl and methyl phosphine substituents of another. In the structure of complex (2), a chain motif of centrosymmetrical dimers is found along [010] through C-H⋯O inter-actions.

The asymmetric unit of the title compound, [Mo(2)(C(5)H(5))(2)(C(7)H(7)S)(2)(CO)(2)], consists of two half-mol-ecules, each molecule lying on a centre of symmetry. The thiol-ate groups function as bridges between the Mo(II) atoms, which adopt a quasi-octa-hedral geometry. In the octa-hedral environment the two ligating S atoms are in a cis arrangement.
