The gas-phase intermediates that resulted from the thermolysis of the single-source precursor Me2N(CH2)(3)Ga(N-3)(2) (6) have been investigated by matrix isolation IR spectroscopy. The fragmentation of 6 occurs above 450 degreesC resulting in equal amounts of HN3 and Ga(N-3). Gallium monoazide was characterized for the first time in argon matrices (v(as)(N-3) at 2106.0 cm(-1) and v(s)(N-3) at 1340.3 cm(-1)). Apart from the azides, the thermolysis products NH3, H2C=CNMe, and HCN resulted in the most intense IR absorptions. Based on the fact that allyldimethylamine was not found among the thermolysis products and in comparison with the fragmentation of compounds of the type Me2N(CH2)(3)MX2 (1-4) a beta -hydrogen elimination can be excluded as the initial fragmentation step of 6.
