Manganese(IV) phosphate is investigated as a novel electrode material for energy storage devices. It consists of manganese(IV) cations, Mn4+\text{Mn}^{4+}Mn4+, and phosphate anions, PO43−\text{PO}_4^{3-}PO43−.
What is the correct chemical formula for manganese(IV) phosphate?
Mn4(PO4)3\text{Mn}_4(\text{PO}_4)_3Mn4(PO4)3
Mn3(PO4)4\text{Mn}_3(\text{PO}_4)_4Mn3(PO4)4
Mn3(PO4)2\text{Mn}_3(\text{PO}_4)_2Mn3(PO4)2
MnPO4\text{Mn}\text{PO}_4MnPO4
