Novel rhodathiaborane complexes derived from [(PPh₃)₂RhSB₉H₁₀]

Abstract

The compound [8,8-(PPh3)2-8,7-RhSB9H10], (1), has a formal closo electron count but a nido structure, exhibits unusual fluxional behaviour in solution and reacts to give both closo and nido compounds, e.g., closo-[2,3-(PPh3)2-3-(Cl)-µ-2; 3-(Cl)-2-(Ph2P[graphic omitted]H8], (2), and nido-[8,8-(PPh3)2-µ-8;9-(S2CH)-8,7-RhSB9H9], (3); the structures of (1), (2), and (3) were determined by X-ray crystallographic methods.
