# Phosphatoantimonate

Phosphatoantimonates are compounds that contain anions that contain phosphorus and antimony in the +5 oxidation state, along with oxygen. Thus they are a compound of phosphate and antimonate, bound together by oxygen.
phosphatoantimonates have been investigated as catalysts, and ion exchange materials.
