mp-20194: CeO2 (cubic, Fm-3m, 225) - Materials Project
CeO2 is Fluorite structured and crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. Ce4+ is bonded in a body-centered cubic geometry to eight equivalent O2- atoms. All Ce–O bond lengths are 2.37 Å. O2- is bonded to four equivalent Ce4+ atoms to form a mixture of edge and corner-sharing OCe4 tetrahedra.
