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:
![{\displaystyle {\ce {2{Pu2Se3}+2{PuH3}->[{\text{1600 °C}}]4{PuSe}+3{H2}}}}](https://wikimedia.org/api/rest_v1/media/math/render/svg/2edee8c41b0e28c75b829e380096614988478748)
Fusion of stoichiometric amounts of pure substances:
![{\displaystyle {\ce {{Pu}+{Se}->[{\text{220–1000 °C}}]PuSe}}}](https://wikimedia.org/api/rest_v1/media/math/render/svg/53a93aa10bdd6c8892cecf19f3f03b24268ee05f)
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.
Its magnetic susceptibility follows the Curie-Weiss law. [5]
