Abstract

Using the SCF-Xα-SW method calculations of the electronic structure of the complexes (Yb O8Fe2)7- and (Yb O8Ga2)7- have been carried out. Results show that there is preferential transfer of charge from the rare-earth and ferric ions onto those oxygen ligands which are found experimentally to form the dominant superexchange paths between the ions.
