Sb2BrCl is Indium-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two Sb2BrCl clusters. Sb(1) is bonded in a single-bond geometry to one Cl(1) atom. The Sb(1)-Cl(1) bond length is 1.79 Å. Br(1) is bonded in a single-bond geometry to one Cl(1) atom. The Br(1)-Cl(1) bond length is 0.91 Å. Cl(1) is bonded in a 3-coordinate geometry to two equivalent Sb(1) and one Br(1) atom.
