Popis: The azidoborazines [Me3N3B2(Me)2B(N3)] and [H3N3B3(N3)3] were prepared from the combination of Me3SiN3 and the chloroborazines [Me3N3B2(Me)2BCl] and (H3N3B3Cl3). The compounds have been characterized by analytical and spectroscopic methods. The molecular structure of [H3N3B3(N3)3] has been confirmed by single-crystal X-ray diffraction techniques: triclinic space group P1 with a = 8.579(1) A, b = 9.182(1) A, c = 12.043(1) A, α = 104.62(1)°, β = 90.26(1)°, γ = 110.74(1)°, and Z = 4. The thermal behavior of the azides have been examined by TGA/DTA. The explosion sensitivity of [H3N3B3(N3)3], which contains 82.58% nitrogen by weight, has been accessed by drop weight impact, spark, and friction tests. These measurements indicate that [H3N3B3(N3)3] is a relatively sensitive explosive. The Staudinger reactivity of the azides with Ph3P was examined, and [H3N3B3(N3)3] was found to produce [Ph3PNH2](N3). The molecular structure of this compound was determined by single-crystal X-ray diffraction techniques: ortho...
