The crystal structure described by Ce2(SO6)3 crystallizes in the monoclinic C2/c space group. Ce(1) is bonded in a 8-coordinate geometry to one O(1), one O(2), one O(4), one O(6), one O(7), one O(8), and two equivalent O(9) atoms. There are two inequivalent S sites. In the first S site, S(1) is bonded in a distorted tetrahedral geometry to one O(1), one O(2), one O(3), and one O(4) atom. In the second S site, S(2) is bonded in a tetrahedral geometry to two equivalent O(5) and two equivalent O(6) atoms. There are nine inequivalent O sites. In the first O site, O(4) is bonded in a distorted single-bond geometry to one Ce(1) and one S(1) atom. In the second O site, O(5) is bonded in a single-bond geometry to one S(2) atom. In the third O site, O(6) is bonded in a distorted bent 150 degrees geometry to one Ce(1) and one S(2) atom. In the fourth O site, O(7) is bonded in a single-bond geometry to one Ce(1) atom. In the fifth O site, O(8) is bonded in a distorted single-bond geometry to one Ce(1) and one O(1) atom. In the sixth O site, O(1) is bonded in a 3-coordinate geometry to one Ce(1), one S(1), and one O(8) atom. In the seventh O site, O(9) is bonded in a water-like geometry to two equivalent Ce(1) atoms. In the eighth O site, O(2) is bonded in a distorted bent 150 degrees geometry to one Ce(1) and one S(1) atom. In the ninth O site, O(3) is bonded in a single-bond geometry to one S(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
