Abstract

The molecular structure of the title compound obtained from the reaction of Os₃(CO)₁₂ with phenylacetylene reveals the unique feature of two alkyne molecules linked through a carbon and an oxygen atom derived from opening of the CO bond of a carbonyl group; two five-membered rings are formed with σ and π bonds to the Os₃ cluster, and a highly asymmetrical bridging carbonyl group is present.
