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.
Reaction of diplutonium triselenide and plutonium trihydride:
Fusion of stoichiometric amounts of pure substances:
Plutonium selenide forms black crystals of a cubic system, space group Fm3m, cell parameters a = 0.57934 nm, Z = 4, 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]
