Autoignition =Indium(I) bromide is a
chemical compound ofindium andbromine . It is a red crystalline compound that is isostructural with β-TlI and has a distorted rock salt structure. Indium(I) bromide is generally made from the elements, heating indium metal with InBr3. It has been used in thesulfur lamp . Inorganic chemistry , it has been found to promote the coupling of α, α-dichloroketones to 1-aryl-butane-1,4-diones. [cite journal | author = C. Peppe and R.

When indium dibromide is dissolved in water, InBr is produced as a, presumably, insoluble red precipitate, that then rapidly decomposes. [cite journal | author = R.
