The compound described by Cs2AsCl6Br crystallizes in the cubic Fm-3m space group. The structure consists of four hydrogen bromide atoms inside a Cs2AsCl6 framework. In the Cs2AsCl6 framework, Cs(1) is bonded to twelve equivalent Cl(1) atoms to form CsCl12 cuboctahedra that share corners with twelve equivalent Cs(1)Cl12 cuboctahedra, faces with six equivalent Cs(1)Cl12 cuboctahedra, and faces with four equivalent As(1)Cl6 octahedra. As(1) is bonded to six equivalent Cl(1) atoms to form AsCl6 octahedra that share faces with eight equivalent Cs(1)Cl12 cuboctahedra. Cl(1) is bonded in a distorted single-bond geometry to four equivalent Cs(1) and one As(1) atom. is represented by the CIF file [CIF]
