K2Cu(ClF)2 crystallizes in the tetragonal I4/mmm space group. K(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 K(1) and two equivalent Cu(1) atoms to form a mixture of face, corner, and edge-sharing ClK4Cu2 octahedra. The corner-sharing octahedra are not tilted. F(1) is bonded in a linear geometry to one K(1) and one Cu(1) atom.
K2Cu(ClF)2 crystallizes in the tetragonal I4/mmm space group. K(1) is bonded in a distorted single-bond geometry to four equivalent Cl(1) and one F(1) atom. All K(1)-Cl(1) bond lengths are 3.17 Å.
