The crystal structure described by NaBaCe2C4O12F crystallizes in the hexagonal P6_3/mmc space group. Na(1) is bonded in a 6-coordinate geometry to six equivalent O(1) atoms. Ba(1) is bonded to twelve equivalent O(2) atoms to form edge-sharing BaO12 cuboctahedra. Ce(1) is bonded in a 10-coordinate geometry to three equivalent O(2), six equivalent O(1), and one F(1) atom. There are two inequivalent C sites. In the first C site, C(1) is bonded in a trigonal planar geometry to three equivalent O(1) atoms. In the second C site, C(2) is bonded in a trigonal planar geometry to three equivalent O(2) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 4-coordinate geometry to one Na(1), two equivalent Ce(1), and one C(1) atom. In the second O site, O(2) is bonded in a distorted single-bond geometry to two equivalent Ba(1), one Ce(1), and one C(2) atom. F(1) is bonded in a linear geometry to two equivalent Ce(1) atoms. is represented by the CIF file [CIF]
