The spinels hаve а generаl fоrmula AIIB2IIIO4. The оxide aniоns form a ccp (fcc) lattice and the cations occupy the tetrahedral or octahedral holes. For NiFe2O4, please answer to the following questions (Please write your answer on a paper and upload the image file in the Assignments) : (a) Determine the CFSEs of Ni2+ occupying the tetraheral and octahedral holes in terms of Δo. You must draw the electron configurations in the energy level diagrams (Note: The oxides are weak-field (high-spin) ligands and Δt ~ (1/2) Δo). (b) Determine the CFSEs of Fe3+ occupying the tetraheral and octahedral holes in terms of Δo. You must draw the electron configurations in the energy level diagrams (Note: The oxides are weak-field (high-spin) ligands and Δt ~ (1/2) Δo). (c) Which cation (Ni2+, Fe3+) prefers the octahedral holes more strongly? Briefly explain your answer. (d) Would you expect NiFe2O4 to form a normal or inverse spinel? Briefly explain your answer.
