Abstract
The complexation energies of H3BXHnMe3-n (X = N, P; n = 0-3) donor-acc eptor complexes have been investigated at the G2(MP2) level of theory. MP2(Full)/6-31G(d) optimized geometries and G2(MP2) calculated comple xation energies are in good agreement with experiment. Increasing meth yl substitutions on 'X' donor atom augments both the basicity of XHnMe 3-n Lewis bases and the stability of complex. The NBO partitioning sch eme suggests that there is no correlation between the charge transfer and the complexation energies. Published by Elsevier Science B.V.
