Abstract
Density functional theory has been applied to study the origin of the inverse and normal trans influence in alkylcobalamins. In order to cover the X-ray structural data available for alkylcobalamins with a variety of axial substituents, geometries of 28 related corrin-containing models have been optimized and analyzed. The BP86/6-31G(d) level of theory was applied which showed good reliability in reproducing the axial bond lengths. Comparison of experimental and calculated data allowed to conclude that the inverse trans influence is not a general feature of cobalamins, as it appeared from the experimental data analysis alone. Inverse trans influence is observed for the series of R groups with increasing bulk and electron donating ability. For the series of R groups having similar medium bulk, but differing significantly in the electron donating ability, normal trans influence was found. Finally, it was determined, that the axial bond lengths correlate well but differently in the two series of R groups with the orbital energies of the six molecular orbitals essential in axial interligand bonding.
