Abstract
The structure of disilazane, (SiH3)2NH, has been determined by the sector microphotometer method of electron diffraction. The Si–N bond length is 1·725 ± 0·003 Å, and the Si–N–Si angle is 127·7°± 0·1°; these results are discussed in terms of (p→d)π-bonding. The Si–H bond length is found to be 1·484 ± 0·006 Å, and the H–Si–H angle to be 108·0°± 1·0°. The conformation of the SiH3 groups and the possibility of a distortion of the N–H bond from the heavy-atom plane have also been studied.Keywords
