Reaction of the tricarbon-yl{η(5)-[2-(dimethyl-amino)eth-yl]cyclo-penta-dien-yl}molybdenum anion and dichlorido-diphenyl-stannane affords the title compound, [MoSn(C(6)H(5))(2)Cl(C(9)H(14)N)(CO)(3)], which exhibits a four-legged piano-stool geometry with chlorido-diphenyl-stannyl ligands unperturbed by the pendant 2-(dimethyl-amino)ethyl groups. The Mo-Sn bond length [2.7584 (5) Å] and the distortion of the tetra-hedral tin coordination geometry are similar to those observed in related tin-substituted tricarbonyl-molybdenum and -tungsten complexes.
