Materials Data on Cs2CaO2 by Materials Project
Cs2CaO2 crystallizes in the orthorhombic Pbcn space group. The structure is three-dimensional. Cs1+ is bonded in a 4-coordinate geometry to four equivalent O2- atoms. There are a spread of Cs–O bond distances ranging from 2.93–3.28 Å. Ca2+ is bonded to four equivalent O2- atoms to form distorted edge-sharing CaO4 tetrahedra. There are two shorter (2.29 Å) and two longer (2.31 Å) Ca–O bond lengths. O2- is bonded in a 6-coordinate geometry to four equivalent Cs1+ and two equivalent Ca2+ atoms.
