A theoretical study of the bonding in trivalent americium complexes
(2004) In Chemical Physics Letters 396(4-6). p.452-457- Abstract
- An account of the electronic structure of AmF3 and AmCl3 has been obtained by Complete Active Space calculations (CASSCF and CASPT2) using either a scalar Douglas-Kroll-Hess Hamiltonian or a relativistic effective core potential. It has been compared to the description obtained by density functional theory (DFT) methods combined with a quasi-relativistic ZORA approach, either in the scalar or two-component approach. Optimised geometries of the ground and first excited states ((7)A(1) and (7)A(2) in C-3v Symmetry) given by both methodologies are similar, which let us conclude that monoconfigurational DFT methods are reliable tools at least for the geometrical and bonding analysis of Am(III) complexes.
