Molecular orbital calculations of the BeF42- and BF4- systems, which are of special interest since they are the principal structural units of fluoroberyllate and fluoroborate glasses, are reported. The calculations were carried out by the nonempirical MO-LCAO-SCF method using the NDDO variant in the valence approximation which had been developed earlier.
