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

💡 Solution & Explanation

Fe$_3$O$_4$ crystallizes in an inverse spinel structure where O$^{2-}$ ions form the complete CCP lattice (not just alternate faces). The divalent Fe$^{2+}$ ions occupy octahedral voids exclusively, while the trivalent Fe$^{3+}$ ions are distributed evenly between tetrahedral and octahedral voids. Therefore, correct answer is A,C.
