The new clusters [MRuCo(CO)8(μ3-Se){η5-C5H4C(O)O Et}](M = Mo 2 or W 3) are isolated from the reaction of [RuCo2(CO)9(μ3-Se)] 1 and [M(CO)3{η5-C5H4C(O)OEt]-(M = Mo or W), and the structure of cluster 2 has been established by single crystal X-ray diffraction methods.

The asymmetric parameter is defined as α = (d2 - d1)/d1 where d2 is the long M…C distance and d1 is the short M–C distance. If 0.1 ≤ α ≤ 0.6, a semibridging carbonyl is designated according to Curtis’ suggestion. CurtisM. D., HanK. R. and ButlerW. M., Inorg. Chem., 1980, 19, 2096.
