Gallium triiodide can be reduced with gallium metal to give a green-colored solid called "gallium(I) iodide." The nature of this species is unclear, but it is useful for the preparation of compounds of gallium(I) and galium(II) and is reported as useful in organic syntheses.<ref>Baker, Robert J.; Jones, Cameron.
