WebSep 27, 2024 · In contrast, it is easy to show that Fe 3 +, which is d 5, would have a CFSE of zero in either the octahedral or tetrahedral geometry.This means that Fe 2 + has a preference for the octahedral site, but Fe 3 + has no preference. Consequently, we place Fe 2 + on octahedral sites and Fe 3 O 4 is an inverse spinel, Fe 3 + (Fe 2 + Fe 3 +)O 4.. Ferrites …
