Neptunium tetraiodide is a hypothetical inorganic compound of neptunium and iodine with the chemical formula NpI₄. ^{[1] [2]} While it has not been discovered, it is expected to be stable. ^[3]

Synthesis

Neptunium tetraiodide was attempted to be obtained by heating neptunium tetrachloride with silicon tetraiodide at 200 °C in vacuo. However, this only resulted in the formation of neptunium(III) iodide. ^[4]
