The corner-sharing octahedral tilt angles are 25°. 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 are 25°. There are three inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to one Na(1), one Sr(2), one Ce(1), and one Bi(1) atom. In the second O site, O(2) is bonded in a 3-coordinate geometry to one Na(2), one Sr(1), one Ce(1), and one Bi(1) atom. In the third O site, O(3) is bonded in a 3-coordinate geometry to one Sr(1), one Sr(2), one Ce(1), and one Bi(1) atom.
