Azidotriphenylsilane: a new determination

I. Wharf and F. Bélanger-Gariépy

Abstract: The title compound, (I), C₁₈H₁₅N₃Si, is monomeric with quasi-tetrahedral geometry around Si. The azide group (-N-N-N) is disordered. One form has (N-N) > d(N-N); the other has d(N-N) < d(N-N). In contrast, the mesityl analogue, (II), has d(N-N) only slightly less than d(N-N). As expected, on going from (I) to (II), d(Si-N), d(Si-C)_ave and angle (C-Si-C)_ave increase, while angle (C-Si-N)_ave decreases.
