Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa).

Neptunium(III) phosphide is a binary inorganic compound of neptunium metal and phosphorus with the chemical formula NpP.[2]

Preparation

[edit]

Neptunium(III) phosphide can be formed from the fusion of stoichiometric amounts of neptunium and phosphorus at 750 °C:[citation needed]

4 Np + P4 → 4 NpP

Physical properties

[edit]

Neptunium(III) phosphide forms black crystals of NaCl-structure.[3] It is insoluble in water. It is antiferromagnetic below 130 K.[4][5]
