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:
Fusion of stoichiometric amounts of pure substances:
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]
