| Abstract: | The reactions of bisbis(trimethylsilyl)methyl]-germylene ( 1 ) and the corresponding stannylene ( 2 ) with di-tert-butyldiazidosilane gave N-(azidosilyl)germanimine ( 4 ) and the stannanimine ( 5 ) in quantitative yields. The structures have been confirmed by single-crystal X-ray diffraction. Crystal data for 4 : space group P1 , Z = 2, a = 9.236 (1), b = 12.066 (1), c = 17.068 (1) Å, α = 98.45 (1), β = 90.43, γ = 110.27 (1)°. V = 1761.3 Å3, R = 0.051, and Rw = 0.069 based on 4218 reflections with |Fo2| ⩾ 3σ|Fo2|. For 5 : space group P1 , Z = 2, a = 9.183 (1), b = 12.193 (1), c = 17.292 (1) Å, α = 98.74 (1), β = 90.21, γ = 109.96 (1)°, V = 1795.5 Å3, R = 0.040, and Rw = 0.051 based on 4795 reflections. The similar reactions of 1 and 2 with 1,3-diazidohexamethyltrisilane ( 16 ) provided azatrisilacyclobutanes quantitatively. |
