Infobox references

Plutonium selenide is a binary inorganic compound of plutonium and selenium with the chemical formula PuSe.[1][2] The compound forms black crystals and does not dissolve in water.

## Synthesis

Reaction of diplutonium triselenide and plutonium trihydride:

2Pu2Se3+2PuH3→1600 °C4PuSe+3H2

Fusion of stoichiometric amounts of pure substances:

Pu+Se→220-1000 °CPuSe

## Properties

Plutonium selenide forms black crystals of a cubic system, space group Fm3m, unit cell dimension a = 0.57934 nm, Z = 4, with structure of the NaCl type.[3][4]

With increasing pressure, two phase transitions occur: at 20 GPa into the trigonal system and at 35 GPa into the cubic system, a structure of the CsCl type.

Its magnetic susceptibility follows the Curie-Weiss law.[5]
