Sr2CuO2Cl2 crystallizes in the tetragonal I4/mmm space group. Sr(1) is bonded in a 9-coordinate geometry to four equivalent O(1) and five equivalent Cl(1) atoms. Cu(1) is bonded in a square co-planar geometry to four equivalent O(1) and two equivalent Cl(1) atoms. O(1) is bonded to four equivalent Sr(1) and two equivalent Cu(1) atoms to form a mixture of face, corner, and edge-sharing OSr4Cu2 octahedra. The corner-sharing octahedra are not tilted. Cl(1) is bonded in a 6-coordinate geometry to five equivalent Sr(1) and one Cu(1) atom.
Sr2CuO2Cl2 crystallizes in the tetragonal I4/mmm space group. Sr(1) is bonded in a 9-coordinate geometry to four equivalent O(1) and five equivalent Cl(1) atoms. All Sr(1)-O(1) bond lengths are 2.63 Å. There are four shorter (3.07 Å) and one longer (3.39 Å) Sr(1)-Cl(1) bond length. Cu(1) is bonded in a square co-planar geometry to four equivalent O(1) and two equivalent Cl(1) atoms. All Cu(1)-O(1) bond lengths are 1.99 Å. Both Cu(1)-Cl(1) bond lengths are 2.93 Å. O(1) is bonded to four equivalent Sr(1) and two equivalent Cu(1) atoms to form a mixture of face, corner, and edge-sharing OSr4Cu2 octahedra. The corner-sharing octahedra are not tilted.
