Which density functional should be used to study actinyl complexes?

Abstract

The new M06 functional of Truhlar and co-workers is found to be competitive with high level ab initio methods in the study of the water exchange mechanism of the [UO(2)(OH(2))(5)](2+) ion, and of the redox potentials of the aqua complexes of [AnO(2)](2+) (An = U, Np and Pu).
