Praseodymium phosphide is an inorganic compound of praseodymium and phosphorus with the chemical formula PrP.[2][3][4] The compound forms crystals.

## Synthesis

Heating metal praseodymium and phosphorus in the presence of iodine vapor:[5]

4Pr+PA4⟶4PrP

## Physical properties

Praseodymium phosphide forms crystals of a cubic system, space group Fm3m, with cell parameters a = 0.5872 nm, Z = 4, and structure like sodium chloride NaCl.[6][7]

The compound melts congruently at 3120 °C.
