Ca3AsBr3 crystallizes in the cubic Pm-3m space group. Ca(1) is bonded to two equivalent As(1) and four equivalent Br(1) atoms to form a mixture of edge and corner-sharing CaAs2Br4 octahedra. The corner-sharing octahedra are not tilted. As(1) is bonded to six equivalent Ca(1) atoms to form corner-sharing AsCa6 octahedra. The corner-sharing octahedra are not tilted. Br(1) is bonded in a square co-planar geometry to four equivalent Ca(1) atoms.
