The structure described by Sr2CeBiO6 crystallizes in the monoclinic P2_1/c space group. Sr(1) is bonded in a 8-coordinate geometry to two equivalent O(3), three equivalent O(1), and three equivalent O(2) atoms. Ce(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form CeO6 octahedra that share corners with six equivalent Bi(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 33-35°. Bi(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form BiO6 octahedra that share corners with six equivalent Ce(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 33-35°. There are three inequivalent O sites. In the first O site, O(1) is bonded in a 5-coordinate geometry to three equivalent Sr(1), one Ce(1), and one Bi(1) atom. In the second O site, O(2) is bonded in a 5-coordinate geometry to three equivalent Sr(1), one Ce(1), and one Bi(1) atom. In the third O site, O(3) is bonded to two equivalent Sr(1), one Ce(1), and one Bi(1) atom to form distorted corner-sharing OSr2CeBi tetrahedra. is represented by the CIF card [CIF]
