what are inverse spinal structures?

Expert Answer:

An inverse spinel is an alternative arrangement where the divalent ions swap with half of the trivalent ions so that the M(II) now occupy octahedral sites
i.e. B(AB)O4The structure of an inverse spinel occurs primarily because certain types of ions with a positive two charge naturally prefer to be in an octahedral and they force the positive-three charge ions out. One example of an inverse spinel structure is Mg2TiO4, while the most common, normal, spinel structure is MgAl2O4.
