Synthesis

Praseoymium monophosphide can be prepared by heating praseodymium and phosphorus in the presence of iodine vapor: [5]

4 Pr + P4 → 4 PrP

Physical properties

Praseodymium monophosphide 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] It melts congruently at 3120 °C.
