3d impurities in normal and inverted perovskites: Differences are not explained by ligand field theory

can hardly be understood within the traditional ligand field theory, which ignores the influence of the electrostatic potential VR r exerted by the rest of the lattice ions upon the localized electrons of the NiF6 4− complex. Although VR r is known to be very flat for a normal perovskite structure, it is shown that this is no longer true for an inverted perovskite. The origin of this significant difference is accounted for by simply considering, for
