Abstract

The reaction of ^tBuNC with the osmium-antimony cluster Os₃(μ-H)(CO)₁₀(μ-SbPh₂) (1) proceeded via Os-Os bond cleavage to give HOs₃(CO)₁₀(μ-SbPh₂)(CNBu^t) (2) in which the ^tBuNC ligand was added onto one of the osmium atoms bridged by the antimony. Cluster 2 exists in isomeric forms, where the ^tBuNC ligand occupies either an axial (a-2) or an equatorial (e-2) position with respect to the Os₃Sb plane. In solution, e-2 was found to occur as a mixture of isomers in which the isonitrile was presumably either cis to the unique osmium or to the antimony.
