Pentanuclear alkoxyaluminium hydrides
Abstract
Reaction of [AlH3(OEt2)] (generated in situ from AlCl3 and 3 equivalents of LiAlH4) with one equivalent of PriOH resulted in the formation of the pentanuclear complex [Al5(μ4-O)(μ-OPri)7H6]. Incomplete reaction of AlCl3 and 3 equivalents of LiAlH4, followed by the addition of PriOH, afforded the novel species [Al5(μ5-O)(μ-OPri)8(Cl)H4]. Both complexes have been structurally characterised.
