Rb2Cu(ClF)2 crystallizes in the tetragonal I4/mmm space group. Rb(1) is bonded in a distorted single-bond geometry to four equivalent Cl(1) and one F(1) atom. Cu(1) is bonded to four equivalent Cl(1) and two equivalent F(1) atoms to form distorted corner-sharing CuCl4F2 octahedra. The corner-sharing octahedra are not tilted. Cl(1) is bonded to four equivalent Rb(1) and two equivalent Cu(1) atoms to form a mixture of edge, corner, and face-sharing ClRb4Cu2 octahedra. The corner-sharing octahedra are not tilted. F(1) is bonded in a linear geometry to one Rb(1) and one Cu(1) atom.
