The crystal structure described by TbCe3O8 is Fluorite-derived structured and crystallizes in the tetragonal I4/mmm space group. Tb(1) is bonded in a body-centered cubic geometry to eight equivalent O(1) atoms. There are two inequivalent Ce sites. In the first Ce site, Ce(1) is bonded in a body-centered cubic geometry to eight equivalent O(1) atoms. In the second Ce site, Ce(2) is bonded in a body-centered cubic geometry to eight equivalent O(1) atoms. O(1) is bonded to one Tb(1), one Ce(2), and two equivalent Ce(1) atoms to form a mixture of corner and edge-sharing OTbCe3 tetrahedra. is represented by the Crystallographic Information File (CIF) [CIF]
