Rb2TeBr6 crystallizes in the cubic Fm-3m space group. Rb(1) is bonded to twelve equivalent Br(1) atoms to form RbBr12 cuboctahedra that share corners with twelve equivalent Rb(1)Br12 cuboctahedra, faces with six equivalent Rb(1)Br12 cuboctahedra, and faces with four equivalent Te(1)Br6 octahedra. Te(1) is bonded to six equivalent Br(1) atoms to form TeBr6 octahedra that share faces with eight equivalent Rb(1)Br12 cuboctahedra. Br(1) is bonded to four equivalent Rb(1) and one Te(1) atom to form a mixture of distorted face, corner, and edge-sharing BrRb4Te square pyramids.
