Reactions of the electron-deficient triosmium cluster [Os 3(CO)9(μ3-η2-C 9H6N)(μ-H)] (1) with various alkynes are described. Cluster 1 readily reacts with the activated alkyne dimethyl acetylenedicarboxylate (dmad) upon mild heating (65-70 °C) to give the adduct [Os3(CO)9(μ-C9H6N) (μ3-MeO2CCCHCO2Me)] (2). In contrast, a similar reaction of 1 with diphenylacetylene affords previously reported compounds [Os3(CO)10(μ-η2-C 9H6N)(μ-H)] (3), [Os3(CO) 9(μ-C4Ph4)] (4) and [Os3(CO) 8{μ3-C(C6H4)C3Ph 3}(μ-H)] (5) while with 2-butyne gives only the known compound [Os3(CO)7(μ-C4Me4) (μ3-C2Me2)] (6). The new cluster 2 has been characterized by a combination of spectroscopic data and single crystal X-ray diffraction analysis.

The reaction of the cluster Os3(CO)10(μ-H) (μ-γ-C5H3O2) (1) with a number of alkynes under thermal or visible light irradiation conditions, afforded in most cases the dinuclear complexes Os2(CO)6(μ-γ-C5 H3O2)(μ-LH) (L=PhCCPh, tBuCCH, tBuCCMe or EtCCEt) (2) or the trinuclear chain complexes Os3(CO)9(μ-H)(μ-γ-C5 H3O2)(μ-RCCHC6H4) (R=H, Ph) (3). In the case of PhCCPh, a new isomer of Os3(CO)8(PhCCPh)2, viz., Os3(CO)8(μ-PhCCPh)(μ-PhCCHC6 H4) (7) has been isolated and characterised.
