N2 - The synthesis of the tetrameric azidoalanes [(CH3)ClAlN3]4 (1) and [(CH3)BrAlN3]4 (2) with heterocyclic cyclooctane-like structures has been demonstrated. X-ray structural determinations reveal that 1 and 2 consist of Al4N4 eight-membered rings in which the Al atoms are bridged by the α nitrogens of the azide groups. [(CH3)ClAlN3]4 (1) crystallizes in the tetragonal space group P2Ic with a = 11.077(4) , c = 8.662(4) , V = 1062.9(8) and Z = 8. [(CH3)BrAlN3]4 (2) crystallizes in the monoclinic space group P2I with a = 8.6702(12) b = 11.1311(15) c = 11.7501(16) , α = 90°, β = 97.913(2)°, γ = 90°, V = 1123.23(3) 3 and Z = 8. The reaction of AlH3•N(CH3)3 with HN3 resulted in formation of an azidoalane with composition close to AlH2N3•N(CH3)3 (3). This compound is unstable with respect to loss of H2 and N(CH3)3 at room temperature.
