Abstract

The molecular geometry (in terms of ra and rg internuclear distances) and mean amplitudes of vibration of CCl3GeCl3 have been determined by electron diffraction. The bond lengths are similar to those found in analogous molecules. Although bond angles of unambiguous physical definition have not been determined it is established that the carbon and germanium bond configurations deviate little from the regular tetrahedral arrangement. The molecule performs large amplitude motion around the carbon-germanium bond. The torsional barrier was estimated to be 1.1 kcal mole-1 using J. Karle's method [8].
