Abstract

The synthesis of [(CH3)ClGaN3]4 (1) with a heterocyclic cyclooctane-like structure and [(CH3)BrGaN3]3 (2) with a trimeric structure has been demonstrated. X-ray structural determinations reveal that 1 and 2 consist of Ga4N4 eight-membered rings and Ga3N3 six-membered rings, respectively, in which the Ga atoms are bridged by the α nitrogens of the azide groups. [(CH3)ClGaN3]4 crystallizes in the tetragonal space group P4̄21c with a = 11.017(4) Å, c = 8.699(7) Å, and Z = 8. [(CH3)BrGaN3]3 crystallizes in the triclinic space group P1̄ with a = 8.1080(10) Å, b = 9.9390(13) Å, c = 10.4439(13) Å, α = 86.069(3)°, β = 86.771(3)°, γ = 80.829(2)°, and Z = 6. The reaction of 1 and 2 with LiGaH4 yields [(CH3)HGaN3](x), which is a new low-temperature source of GaN.
