Consider a transition-metal complex of formula ML₄ Using the angular overlap model and assuming trigonalbipyramidal geometry, determine the energies of the d orbitals

a. considering sigma interactions only (assume L and are similar in donor ability).

b. considering as a π acceptor as well. Consider in both (1) axial and (2) equatorial positions.

c. based on the preceding answers, would you expect π -acceptor ligands to preferentially occupy axial or equatorial positions in five-coordinate complexes? What other factors should be considered in addition to angular overlap?
