Neptunium(IV) nitrate is an inorganic compound, a salt of neptunium and nitric acid with the chemical formula Np(NO3)4.[1][2][3] The compound forms gray crystals, dissolves in water, and forms crystal hydrates.[4][5]

Synthesis

Addition of dilute nitric acid to freshly prepared neptunium(IV) hydroxide:[6][7]

[math]\displaystyle{ \mathsf{ Np(OH)_4 + 4HNO_3 \ \xrightarrow{}\ Np(NO_3)_4 + 4H_2O } }[/math]

Physical properties

Neptunium(IV) nitrate forms gray hygroscopic crystals.

It is soluble in water.

It forms a crystal hydrate of the composition Np(NO3)4•2H2O.
