Abstract

The molecular geometry of gaseous triphenylsilane has been determined by electron diffraction. The silicon bond angles are ideal tetrahedral within experimental error. The benzene rings are slightly elongated in the direction of the SiC bond. The experimental data are consistent with a C3 model and a mean torsional angle of 37°, in agreement with published molecular mechanics calculations. The electron diffraction bond lengths (with estimated total errors), among them rg(SiC) 1.872(4) Å and rg(CC mean) 1.403(3) Å, refer to a well-defined nuclear configuration and differ from the analogous parameters from an X-ray crystallographic study of the same molecule.
