SURPRISING STABILITY OF A MONOMERIC BIS AZIDE OF GALLIUM(III)

The intramolecularly base-stabilized arylgallium diazide [2,6-(Me(2)NC H(2))(2)C6H3]Ga(N-3)(2) (1) has been prepared by a metathetical reacti on of the corresponding arylgallium dichloride with NaN3. Compound 1 w as found not only to be air stable, but also to survive vapor phase he ating at 400 degrees C or UV irradiation at 254 nm. The X-ray crystal structure of 1 has been determined; triclinic, P (1) over bar, with a = 8.861(2), b = 10.445(4), c = 11.562(4) Angstrom alpha = 107.07(3), b eta = 105.92(2), gamma = 101.35(3)degrees, V = 937.9(5) Angstrom(3) an d Z = 2. Compound 1 is monomeric in the solid state.
