Which of the following is/are correct statement(s) about Fe3O4 crystal? — Solid State Chemistry Question

💡 Solution & Explanation

Fe3O4 crystallizes in an inverse spinel structure where $O_2$- forms a CCP lattice. Fe2+ ions occupy octahedral voids, and Fe3+ ions are equally distributed between tetrahedral and octahedral voids. Therefore, (a), (b), and (c) are correct. $O_2$- ions occupy all FCC positions, not alternate faces.
