Indium(II) chloride is an hypothetical inorganic compound with the formula . Its existence have been disproved and the substance claimed to be indium(II) chloride is a mixture of various indium subchlorides.
History.
Indium(II) chloride was first reported to be produced in 1888 by Lars Fredrik Nilson who claimed to have produced indium(II) chloride from the reaction of indium metal and hydrogen chloride gas at 200 °C. However, this has been called into doubt as characterization by X-ray diffraction and NMR failed. 
In 1983, an investigation found that the solid claimed to be indium(II) chloride is actually a 5:1 mixture of In5Cl9, alternatively formulated In3[In2Cl9], and InCl3.
