    • To gain an understanding of the relative stabilities of two methylcopper-substrate (d-π*) complexes, we undertook ab initio calculations at the RHF/LANL1DZ level of theory. Effective core potential (ECP) for Cu and double-ξ were used for other elements. To reduce the size, two model systems A and B of methylcopper-substrate (d-π*) complexes were chosen. However, it was found that the energy difference between geometries A and B was predicted to be only 0.387 kcal/mol. Figure presented
