Suppose that a transition-metal ion was in a lattice in which it was in contact with just two nearby anions, located on opposite sides of the metal. Diagram the splitting of the metal d orbitals that would result from such a crystal field Assuming a strong field, how many unpaired electrons would you expect for a metal ion with six d electrons? (Hint: Consider the linear axis to be the z-axis)
