TABLE 11. Calculated mean M—X bond dissociation energies (kcal mol-1) in MXq (experimental values are given in parentheses ) 

6 At B3LYP, including ZPE and atomic spin-orbit corrections from Reference 153. 

The geometries of all (CH3) MCl4 (M = C to Pb)152 were optimized using allelectron 3-21G(d), 6-31G(d) and ECP basis sets in order to evaluate the performance
