A x B y O z ‐type complex oxides with multiple cations show different chemical ordering for the cations at the A and B sites. In their Communication on page 7963 ff., S.‐Y. Chung et al. report the configurational ordering in an AB 2 O 4 spinel by the formation of Frenkel defects at octahedral sites as a transient state. The role of such point defects in crystals is not confined merely to mass and charge transport but extends to phase transitions.
