Abstract
In the title compound, [MoPb(C5H5)(CH3COO)(CO)3], the PbII atom is coordinated pyramidally via the Mo0 atom of a {Cp(CO)3Mo} (Cp = cyclopentadienyl) 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) interactions, giving a ladder-type polymeric structure composed of PbCO2 and Pb2O2 four-membered rings. The {Cp(CO)3Mo} units attached to the PbII 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)°.
