The material structure described by Ce(HCOO)3 crystallizes in the trigonal R3m space group. Ce(1) is bonded in a 9-coordinate geometry to three equivalent O(1) and six equivalent O(2) atoms. C(1) is bonded in a trigonal planar geometry to one H(1), one O(1), and one O(2) atom. H(1) is bonded in a single-bond geometry to one C(1) atom. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to one Ce(1) and one C(1) atom. In the second O site, O(2) is bonded in a distorted single-bond geometry to two equivalent Ce(1) and one C(1) atom. is represented by the CIF file [CIF]
