Fe_3O_4 has inverse spinel structure. What is not true about this solid ?

Answer»

`FE^(3+)` ions are EQUALLY distributed between octahedral and tetrahedral voids
Tetrahedral voids are equally distributed between `Fe^(2+)` and `Fe^(3+)` ions
No. of `O^(-2) gt Fe^(+3) gt Fe^(+2)`
Coordination no. of `Fe^(3+)` =8 through out the unit cell
