Neptunium tetraiodide is a hypothetical inorganic compound of neptunium and iodine with the chemical formula . While it has not been discovered, it is expected to be stable.
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.
