Plutonium(III) phosphide is a binary inorganic compound of plutonium and phosphorus with the formula PuP.

Synthesis

Fusion of excess phosphorus and powdered plutonium, followed by distillation of unreacted phosphorus:

4 Pu + P₄ → 4 PuP

Passing phosphine through heated plutonium hydride:

PuH₃ + PH₃ → PuP + 3 H₂

Physical properties

Plutonium(III) phosphide forms black crystals of a cubic system, space group Fm3m, cell parameters a = 0.5660 nm, Z = 4, structure of the NaCl type.
