Indium monoiodide is a binary inorganic compound of indium metal and iodine with the chemical formula InI.[1][2]

Preparation

Indium(I) iodide can be obtained by reacting indium with iodine or indium(III) iodide in vacuum at 300 °C to 400 °C or with mercury(II) iodide at 350 °C.[3]

2In + I2 → 2InI[4]
2In + InI3 → 3InI
2In + HgI2 → 2InI + Hg

Physical properties

Indium(I) iodide forms a brown-red diamagnetic solid. Its melt is black. The compound has an orthorhombic crystal structure in the space group Cmcm (space group no. 63) with the lattice parameters a = 475 pm, b = 1276 pm, c = 491 pm.[5]

Chemical properties

Decomposes slowly with hot water:

2InI + H2O → InOH + HI

Reacts with water in the presence of oxygen:[6]

2InI + O + 3H2O → 2In(OH)2 + 2HI
