Chemical compound

Praseodymium(III) phosphate is an inorganic compound with the chemical formula PrPO4.

Preparation

Praseodymium(III) phosphate hemihydrate can be obtained by reacting praseodymium chloride and phosphoric acid:

PrCl3 + H3PO4 → PrPO4 + 3 HCl

It can also be produced by reacting silicon pyrophosphate (SiP2O7) and praseodymium(III,IV) oxide (Pr6O11) at 1200 °C.

Properties

Praseodymium(III) phosphate forms light green crystals in the monoclinic crystal system, with space group P21/n and cell parameters a = 0.676 nm, b = 0.695 nm, c = 0.641 nm, β = 103.25°, Z = 4.

It forms a crystal hydrate of the composition PrPO4·nH2O, where n < 0.5, with light green crystals of hexagonal crystal system, space group P6222, and cell parameters a = 0.700 nm, c = 0.643 nm, Z = 3.

Praseodymium(III) phosphate reacts with sodium fluoride to obtain Na2PrF2(PO4).

PrPO4 + 2 NaF → Na2PrF2(PO4)
