The decrease in the negative charge of the metallic unit leads to a lowering of the orbitals of this unit, while the decrease of the positive charge of the allylic unit leads to a rise of the π orbitals of this unit. As a result, the energy gap between the two sets of orbitals becomes larger and the corresponding four-electron repulsions smaller
