CeH(CO2)3 crystallizes in the orthorhombic Pna2_1 space group. Ce(1) is bonded in a 9-coordinate geometry to one O(4), one O(5), one O(6), two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms. There are three inequivalent C sites. In the first C site, C(1) is bonded in a trigonal planar geometry to one H(1), one O(1), and one O(5) atom. In the second C site, C(2) is bonded in a distorted bent 120 degrees geometry to one O(2) and one O(4) atom. In the third C site, C(3) is bonded in a distorted bent 120 degrees geometry to one O(3) and one O(6) atom. H(1) is bonded in a single-bond geometry to one C(1) atom. There are six inequivalent O sites. In the first O site, O(4) is bonded in a distorted bent 120 degrees geometry to one Ce(1) and one C(2) atom. In the second O site, O(5) is bonded in a distorted single-bond geometry to one Ce(1) and one C(1) atom. In the third O site, O(6) is bonded in a distorted bent 120 degrees geometry to one Ce(1) and one C(3) atom. In the fourth O site, O(1) is bonded in a distorted single-bond geometry to two equivalent Ce(1) and one C(1) atom. In the fifth O site, O(2) is bonded in a distorted single-bond geometry to two equivalent Ce(1) and one C(2) atom. In the sixth O site, O(3) is bonded in a distorted single-bond geometry to two equivalent Ce(1) and one C(3) atom.
