|Title:||Axial and equatorial isomers in an isonitrile-substituted osmium-antimony cluster|
|Citation:||Chen, G.,Leong, W.K. (1999-02-18). Axial and equatorial isomers in an isonitrile-substituted osmium-antimony cluster. Journal of Organometallic Chemistry 574 (2) : 276-278. ScholarBank@NUS Repository.|
|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)(CNBut) (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.|
