    In the cubic structure of both iron oxides, one-third of interstices arecoordinated with oxygen ions in a tetrahedralstructure, while two-thirds are bonded in octahedral sites. The key difference between Fe 3 O 4 and γ-Fe 2 O 3 is that in the case of Fe 3 O 4 , Fe 2+ is in eight tetrahedral sites, while Fe 3+ ions occupy 16 octahedral sites in a unit cell.
