Heterobimetallic B-frame compounds: systematic synthesis and molecular structure of the seven-vertex µ-HOs,Pt-nido-osmaplatinaborane [(Ph3P)2(CO)(Os)(PhMe2P)ClHPtB5H7]

Abstract

The first structurally characterized polyhedral metallaborane osmium compound has a seven-vertex nido-osmaplatinaborane cluster structure based on the dodecahedron with one five-connected vertex missing, the metal atoms being located on adjacent (2,7) positions in the five-membered open face and linked via an Os–H–Pt bridging bond; important wider implications of the mechanism of formation are indicated.
