Abstract

Five-coordinate gallium and aluminium dihydrides, H₂Ga[N(CH ₂CH₂NMe₂)₂] (1) and H ₂Al[N(CH₂CH₂NMe₂)₂] (3), were synthesized and found to be volatile and thermally stable. 1 and 3 reacted with H₃Ga(NMe₃) and H₃Al(NMe₃), respectively, to form H₂Ga[N(CH₂CH₂NMe ₂)₂]GaH₃ (2) and H₂Al[N(CH ₂CH₂NMe₂)₂]AlH₃ (4), in which the amido nitrogen bridged between the MH₂ and MH₃ groups (M = Ga or Al). A mixed metal complex, H₂Al[N(CH ₂CH₂NMe₂)₂]GaH₃ (5) was obtained from the reaction of 1 with H₃Al(NMe₃) or 3 with H₃Ga(NMe₃), and a crystal consisting of a mixture of 5 and 2 was structurally characterized. The five-coordinate chloro derivative, Cl₂Ga[N(CH₂CH₂NMe₂)₂] (6), was synthesized and characterized.
