Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa).

Plutonium (IV) nitrate is an inorganic compound, a salt of plutonium and nitric acid with the chemical formula Pu(NO3)4. The compound dissolves in water and forms crystalline hydrates as dark green crystals.[1][2]

Crystals of dark green to black-green composition Pu(NO3)4•5H2O precipitate with a slow (months) evaporation of a solution of a plutonium (IV) compound in nitric acid.[3][4]

Physical properties

Plutonium (IV) nitrate forms a crystalline hydrate of the composition Pu(NO3)4•5H2O—dark green crystals of rhombic crystal structure, space group F dd2, cell parameters: a = 1.114 nm, b = 2.258 nm, c = 1.051 nm, Z = 8.

Crystalline hydrate melts in its own crystallization water at 95–100 °C.

It dissolves well in nitric acid (dark green solution) and water (brown solution). Also dissolves in acetone and ether.
