Ba2CeBiO6 is Orthorhombic Perovskite-derived structured and crystallizes in the monoclinic P2_1/c space group. Ba(1) is bonded in a 9-coordinate geometry to three equivalent O(1), three equivalent O(2), and three equivalent O(3) 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 21-23°. 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 21-23°. There are three inequivalent O sites. In the first O site, O(1) is bonded in a 5-coordinate geometry to three equivalent Ba(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 Ba(1), one Ce(1), and one Bi(1) atom. In the third O site, O(3) is bonded in a 4-coordinate geometry to three equivalent Ba(1), one Ce(1), and one Bi(1) atom.
