The compound described by Ce(WO4)2 crystallizes in the monoclinic C2/c space group. Ce(1) is bonded in a 8-coordinate geometry to two equivalent O(3), two equivalent O(4), and four equivalent O(2) atoms. W(1) is bonded in a 5-coordinate geometry to one O(1), one O(2), one O(3), and two equivalent O(4) atoms. There are four inequivalent O sites. In the first O site, O(1) is bonded in a single-bond geometry to one W(1) atom. In the second O site, O(2) is bonded in a 3-coordinate geometry to two equivalent Ce(1) and one W(1) atom. In the third O site, O(3) is bonded in a bent 150 degrees geometry to one Ce(1) and one W(1) atom. In the fourth O site, O(4) is bonded in a distorted trigonal non-coplanar geometry to one Ce(1) and two equivalent W(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
