Irradiation of the carbonyl(η⁵:η⁵-fulvalene)di-metal complexes of molybdenum, tungsten, and ruthenium 1, 3, and 4 in the presence of alkynes gives not only complexes of different respective composition and structure within the series but also in comparison with the corresponding (η⁵-cyctopentadienyl)metal carbonyl dimers. (η⁵:η⁵-C₁₀H₈)(CO) ₅MoRu (5) furnishes a novel reactive dinuclear (alkyne)metal oxo complex.
