Sr2CoO2Cl2 is (La,Ba)CuO4-derived structured and 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. Co(1) is bonded to four equivalent O(1) and two equivalent Cl(1) atoms to form distorted corner-sharing CoCl2O4 octahedra. The corner-sharing octahedra are not tilted. O(1) is bonded to four equivalent Sr(1) and two equivalent Co(1) atoms to form a mixture of edge, face, and corner-sharing OSr4Co2 octahedra. The corner-sharing octahedra are not tilted. Cl(1) is bonded in a 6-coordinate geometry to five equivalent Sr(1) and one Co(1) atom.
Sr2CoO2Cl2 is (La,Ba)CuO4-derived structured and 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 2.60 Å. There are four shorter (3.06 Å) and one longer (3.24 Å) Sr(1)-Cl(1) bond length. Co(1) is bonded to four equivalent O(1) and two equivalent Cl(1) atoms to form distorted corner-sharing CoCl2O4 octahedra. The corner-sharing octahedra are not tilted. All Co(1)-O(1) bond lengths are 2.02 Å. Both Co(1)-Cl(1) bond lengths are 2.74 Å. O(1) is bonded to four equivalent Sr(1) and two equivalent Co(1) atoms to form a mixture of edge, face, and corner-sharing OSr4Co2 octahedra. The corner-sharing octahedra are not tilted. Cl(1) is bonded in a 6-coordinate geometry to five equivalent Sr(1) and one Co(1) atom.
