Rb2ZrCl6 crystallizes in the cubic Fm-3m space group. Rb(1) is bonded to twelve equivalent Cl(1) atoms to form RbCl12 cuboctahedra that share corners with twelve equivalent Rb(1)Cl12 cuboctahedra, faces with six equivalent Rb(1)Cl12 cuboctahedra, and faces with four equivalent Zr(1)Cl6 octahedra. Zr(1) is bonded to six equivalent Cl(1) atoms to form ZrCl6 octahedra that share faces with eight equivalent Rb(1)Cl12 cuboctahedra. Cl(1) is bonded in a distorted single-bond geometry to four equivalent Rb(1) and one Zr(1) atom.
