Neptunium(III) iodide is the iodide of neptunium with the chemical formula NpI3.
Preparation
Neptunium(III) iodide can be produced by the reaction of neptunium dioxide and aluminium iodide:[3]
- 6 NpO2 + 8 AlI3 → 6 NpI3 + 4 Al2O3 + 3 I2
Properties
Neptunium(III) iodide is a hygroscopic brown solid with a melting point of 767 °C. It is orthorhombic (plutonium(III) bromide structure), space group Ccmm (No. 63), lattice parameters a = 430pm, b = 1403pm and c = 995pm.[4]
