Antimonate - Wikipedia

Sodium antimonate, NaSbO 3, has the ilmenite structure, with hexagonal close packed oxide ions with each ion, Na + and Sb 5+ occupying a third of the octahedral sites. MgSb 2 O 6 has the trirutile structure, which is similar to the rutile structure except that there are two different cations in the lattice.
