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:
- [math]\ce{ 2 {Pu2Se3} + 2 {PuH3} ->[\text{1600 °C}] 4 {PuSe} + 3 {H2} }[/math]
Fusion of stoichiometric amounts of pure substances:
- [math]\ce{ {Pu} + {Se} ->[\text{220–1000 °C}] PuSe }[/math]
Properties
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.
Does not dissolve in water.
Magnetic susceptibility follows Curie-Weiss law.[5]
