Plutonium(III) phosphide is a binary inorganic compound of plutonium and phosphorus with the formula PuP.[2][3]
Synthesis
[edit]Fusion of excess phosphorus and powdered plutonium, followed by distillation of unreacted phosphorus:[4]
- 4 Pu + P4 → 4 PuP
Passing phosphine through heated plutonium hydride:
- PuH3 + PH3 → PuP + 3 H2
Physical properties
[edit]Plutonium(III) phosphide forms black crystals of a cubic system, space group Fm3m,[5] cell parameters a = 0.5660 nm, Z = 4, structure of the NaCl type.[6][7]
