Gold monoiodide (AuI) is a chemical compound of gold and iodine. This compound is commercially available. It can be synthesized by heating gold and iodine in a sealed tube at 120°C for about four months. It decomposes when treated with hot water.^[2] But its related complexes are much more stable.^[3]
