Materials Data on Sr2Co(ClO)2 by Materials Project
Sr2CoO2Cl2 is (La,Ba)CuO4-derived structured and crystallizes in the orthorhombic Immm space group. The structure is three-dimensional. Sr2+ is bonded in a 9-coordinate geometry to four O2- and five equivalent Cl1- atoms. There are two shorter (2.58 Å) and two longer (2.67 Å) Sr–O bond lengths. There are four shorter (3.13 Å) and one longer (3.30 Å) Sr–Cl bond lengths. Co2+ is bonded to four O2- and two equivalent Cl1- atoms to form distorted corner-sharing CoCl2O4 octahedra. The corner-sharing octahedral tilt angles are 0°. There are two shorter (2.01 Å) and two longer (2.13 Å) Co–O bond lengths. Both Co–Cl bond lengths are 2.72 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded to four equivalent Sr2+ and two equivalent Co2+ atoms to form a mixture of distorted face, edge, and corner-sharing OSr4Co2 octahedra. The corner-sharing octahedral tilt angles are 0°. In the second O2- site, O2- is bonded to four equivalent Sr2+ and two equivalent Co2+ atoms to form a mixture of face, edge, and corner-sharing OSr4Co2 octahedra. The corner-sharing octahedral tilt angles are 0°. Cl1- is bonded in a 6-coordinate geometry to five equivalent Sr2+ and one Co2+ atom.
