摘要：

The crystal structure of the phosphide-bridged cluster [Os-6(mu-H)(CO)(21)(NCMe)(mu-PH2)] 4 has been determined. The cluster consists of two Os-3 triangles which are linked by a PH2, moiety which is terminally bound to each triangle. The acetonitrile ligand is axially coordinated and the hydride bridges the Os-Os edge to which the phosphide moiety and the acetonitrile are coordinated. The molecular structure of 4 resembles those of the related clusters [Os-6(mu-H)(CO)(22)(mu-PH2)] 1 and [Os-6(mu-H)(CO)(21)(CNBut)(mu-PH2)] 2 although the dihedral angles between the two osmium triangles vary for 1, 2 and 4. The relative orientation of the two linked metal triangles in 4 (as well as 1 and 2) differs from that of the phosphite-substituted analogue [Os-6(mu-H)(CO)(20)(P(OMe)(3))(2)(mu-PH2)](3); this difference is attributed to steric factors.
