Preparation and crystal structures of oxoosmium(VI) diolato complexes
Abstract
Reaction of OsO4 with one equivalent of PPh3 in the presence of the tertiary diols, 2,3-dimethyl-2,3-butanediol (H2pin) and 1,1′-bicyclohexane-1,1′-diol (H2bicy), afforded the new oxoosmium(VI) complexes [OsO(diol)2]. The molecular structures of [OsO(pin)2], [OsO(bicy)2] and its adduct [OsO(bicy)2]·H2bicy·PPh3O were determined by X-ray crystallography.
