Materials Data on CsCoO2 by Materials Project
CsCoO2 crystallizes in the cubic Fd-3m space group. The structure is three-dimensional. Cs1+ is bonded in a 12-coordinate geometry to twelve equivalent O2- atoms. All Cs–O bond lengths are 3.56 Å. Co3+ is bonded to four equivalent O2- atoms to form corner-sharing CoO4 tetrahedra. All Co–O bond lengths are 1.86 Å. O2- is bonded in a linear geometry to six equivalent Cs1+ and two equivalent Co3+ atoms.
