The synthesis and molecular structure of 9-H-9,9-(Et3P)210,11-H-7,8,9-C2PtB8H10and 9-H-9,10-(Et3P)2-7,8,9-C2PtB8H9; Pt(9)→ B(10) migration of a triethylphosphine ligand, and evidence for the redox sequence Pt0→ PtIV→ PtII

Abstract
Reaction of [Pt2(µ-cyclo-octa-1,5-diene)(PEt3)4] with 5,6-dicarba-nido-decaborane affords 9-H-9,9-(Et3P)2-µ10,11-H-7,8,9-C2PtB8H10, which on pyrolysis (100 °C) loses H2 and forms 9-H-9,10-(Et3P)2-7,8,9-C2PtB8H9; the structures of these compounds have been determined by X-ray crystallography.
