Abstract

We discuss the validity of the usually used orbital radii capable to separate differently coordinated compounds in efficient structural maps. In order to account for the real dependence on the angular momentum, we redefine the atomic terms by including the d-states contribution, previously ignored. The choice of the right amount of the correction has been performed thanks to a series of structural maps obtained through a computer-aided code.
