A series of new hexafunctional tetrasilylmethane derivatives, C[Si(CH3)2X]3SiX3, have been prepared. In addition a comprehensive structural study of the parent compound C[Si(CH3)2H]3SiH3 has been undertaken. A full search of the potential energy surface has been performed ab initio. Results indicate the presence of a total of eleven distinct conformational minima with a total energy range of only 3 kJ mol-1, with evidence for appreciable energy barriers to internal rotation. The analysis of gas-phase electron diffraction data has been undertaken for this eleven-conformer model and a satisfactory fit has been obtained.
