Structural aspects of tertiary amine adducts of alane and gallane

Article abstract of DOI:10.1016/s0020-1693(97)05465-0

Structures of N-bound alane (AlH₃) and gallane (GaH₃) are reported: the dimethylbenzylamine adduct of gallane, [(PhCH₂(Me)₂NGaH₃], which is monomeric with four-coordinate Ga, and the first chlorine containing amino complex of alane, [ClCH₂CH₂CH₂(Me)₂NAlH ₃]₂, revealing that hydride bridging is favoured over Al-Cl interaction in Al obtaining a five-coordination environment. Also presented is a reinvestigation of the previously poorly defined structural determination of the trimethylamine adduct of gallane, [Me₃NGaH₃].
