Indium(III) bromide

Indium(III) bromide, (indium tribromide), InBr3, is a chemical compound of indium and bromine. It is a Lewis acid and has been used in organic synthesis.It has the same crystal structure as aluminium trichloride, with 6 coordinate indium atoms. When molten it is dimeric, In2Br6, and it is predominantly dimeric in the gas phase. The dimer has bridging bromine atoms with a structure similar to dimeric aluminium trichloride Al2Cl6.It is formed by the reaction of indium and bromine.InBr3 forms complexes with ligands, L, InBr3L, InBr3L2, InBr3L3.
