The number of manganese ions in tetrahedral and octahedral sites, respectively in$\mathrm{M}{\mathrm{n}}_3{\mathrm{O}}_4$are one$\mathrm{M}{\mathrm{n}}^{2+}$and two$\mathrm{M}{\mathrm{n}}^{3+}$ions.
$\mathrm{M}{\mathrm{n}}_3{\mathrm{O}}_4$has spinal type structure in which$\mathrm{M}{\mathrm{n}}^{2+}$occupy 1/8 T.V. and$\mathrm{M}{\mathrm{n}}^{3+}$occupy half of O.V.
Oxide ion has ccp arrangement (corner + face).
