catena-Poly[[tricarbonyl-1κ³C-(1η5-cyclo-penta-dien-yl)lead(II)molyb-denum(0)](Mo-Pb)-µ3-acetato-2':2:2''κ4O:O,O':O'].

In the title compound, [MoPb(C5H5)(CH3COO)(CO)3], the Pb(II) atom is coordinated pyramidally via the Mo(0) atom of a {Cp(CO)3Mo} (Cp = cyclo-penta-dien-yl) fragment [Pb-Mo = 3.0589 (5) Å] and a chelating acetate (Ac) group. Additionally, the [{Cp(CO)3Mo}PbAc] units are linked along [100] by Pb-O(acetate) inter-actions, giving a ladder-type polymeric structure composed of PbCO2 and Pb2O2 four-membered rings. The {Cp(CO)3Mo} units attached to the Pb(II) atom occupy terminal positions at opposite sides of the slightly puckered lead acetate chain. The angle between the Pb-Mo bond vector and the central chain plane is 67.8 (2)°.
