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.[2]
It has the same crystal structure as aluminium trichloride, with 6 coordinate indium atoms.[3] 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 trichlorideAl2Cl6.[3]
It is formed by the reaction of indium and bromine.[4] InBr3 forms complexes with ligands, L, InBr3L, InBr3L2, InBr3L3.[3]
Reaction with indium metal forms lower valent indium bromides, InBr2, In4Br7, In2Br3, In5Br7, In7Br9, indium(I) bromide.[5][6][7][8] In refluxing xylene solution InBr3 and In metal react to form InBr2.[9]
