The structure described by Cs2CeO3 crystallizes in the orthorhombic Cmc2_1 space group. Cs(1) is bonded in a 6-coordinate geometry to two equivalent O(2) and four equivalent O(1) atoms. Ce(1) is bonded in a 5-coordinate geometry to one O(2) and four equivalent O(1) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 6-coordinate geometry to four equivalent Cs(1) and two equivalent Ce(1) atoms. In the second O site, O(2) is bonded in a 1-coordinate geometry to four equivalent Cs(1) and one Ce(1) atom. is represented by the CIF file [CIF]
