AsBrCl is Indium-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two AsBrCl clusters. As(1) is bonded in a linear geometry to one Br(1) and one Cl(1) atom. The As(1)-Br(1) bond length is 1.13 Å. The As(1)-Cl(1) bond length is 0.18 Å. Br(1) is bonded in a distorted single-bond geometry to one As(1) atom. Cl(1) is bonded in a single-bond geometry to one As(1) atom.
