N2 - Reaction of the labilised cluster [Os6(CO)17(NCMe)] with the terminal alkynes HC≡CR (R = Me, Et, or Ph) affords the isomeric alkyne substituted clusters [Os6(CO)17(μ-H) (μ4-η-CCR)] [R = Me (1), Et (3), or Ph (5)] and [Os 6(CO)17(μ4-η2-HCCR)] [R = Me (2), Et (4), or Ph (6)], and under similar conditions the disubstituted alkynes RC=CR′ (R = Me or Ph; R′ = Me, Ph, or Et) give [Os 6(CO)16(μ3-η-RCCR′)] [R = R′ = Me (7); R = R′ = Ph (8); R = Me, R′ = Et (9)] as the major product; the structures of complexes (3), (4), and (9) have been established by X-ray diffraction studies.
