CeCP2H2O6 crystallizes in the monoclinic C2/m space group. Ce(1) is bonded in a 8-coordinate geometry to two equivalent O(2), two equivalent O(3), and four equivalent O(1) atoms. C(1) is bonded in a distorted tetrahedral geometry to two equivalent P(1), one H(1), and one H(2) atom. P(1) is bonded to one C(1), one O(1), one O(2), and one O(3) atom to form distorted corner-sharing PCO3 tetrahedra. There are two inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to one C(1) atom. In the second H site, H(2) is bonded in a single-bond geometry to one C(1) atom. There are three inequivalent O sites. In the first O site, O(3) is bonded in a distorted bent 150 degrees geometry to one Ce(1) and one P(1) atom. In the second O site, O(1) is bonded in a distorted single-bond geometry to two equivalent Ce(1) and one P(1) atom. In the third O site, O(2) is bonded in a water-like geometry to one Ce(1) and one P(1) atom.
