Abstract
The close-type eleven-vertex metallaboranes [PPh3)2RuB10H8(OEt)2] and [(PMe2Ph)2OsB10H8(OEt)2] readily react with a second metal centre [M′Cl2(PPh3)3](M′= Ru or Os) to yield the novel mixed-valance bimetallic species [(PPh3)2ClM′ClM(PR3)B10H8(OEt)2] in which the second metal centre is bound exopolyhedrally to the original cluster in a remarkable way by converting two terminal B–Ht groups into two electron M′–Hµ–B links and involving one terminal M′–Cl group in a third link to the cluster via a four-electron M′–Cl–M bridge; the original cluster metal M remains a sixteen-electron centre but can be readily converted into an eighteen-electron one by replacement of phosphine ligand by bidentate chelates such as CH2(PPh2)2(dppm).
