Praseodymium(III) molybdate is a salt of praseodymium and molybdic acid with the chemical formula Pr2(MoO4)3.

It forms crystals that are insoluble in water.

Praseodymium(III) molybdate crystallizes in the monoclinic crystal system, superspace group I2/b(αβ0)00, cell parameters a = 0.530284 nm, b = 0.532699 nm, c = 1.17935 nm and β = 90.163°.

[2] Several phase transitions occur in crystals at temperatures of 235 and 987 °C.
