Reactions of H2Os3(CO)10 with the diyne ligand HOCH2C2C2CH2OH and its dicobalthexacarbonyl derivatives {CO2(CO)6}(μ2,η2-HOCH2C2C2CH2OH) and {Co2(CO)6}2(μ2,η2 : μ2,η2-HOCH2C2C2CH2OH) have been studied. The reaction of the uncomplexed ligand yields the cluster ▪ with the completely rearranged starting ligand. The structure of this compound was determined by a single-crystal X-ray study. The rearranged ligand forms a pseudo-furan ring with the CCH3 substituent in the α-position. The reactions of H2Os3(CO)10 with the both dicobalthexacarbonyl derivatives yield the (μ-H)(μ-OH)Os3(CO)10 cluster ar the main osmium-containing product. The structure of this compound was also established by a single-crystal X-ray study.
