Na3Ce is alpha bismuth trifluoride structured and crystallizes in the cubic Fm-3m space group. There are two inequivalent Na sites. In the first Na site, Na(1) is bonded in a body-centered cubic geometry to four equivalent Na(2) and four equivalent Ce(1) atoms. In the second Na site, Na(2) is bonded in a 14-coordinate geometry to eight equivalent Na(1) and six equivalent Ce(1) atoms. Ce(1) is bonded in a distorted body-centered cubic geometry to six equivalent Na(2) and eight equivalent Na(1) atoms.
