The structure described by TbH(CO2)3 crystallizes in the orthorhombic Pnma space group. Tb(1) is bonded in a 9-coordinate geometry to one O(2), two equivalent O(1), two equivalent O(3), and four equivalent O(4) atoms. There are two 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(2) atom. In the second C site, C(2) is bonded in a distorted bent 120 degrees geometry to one O(3) and one O(4) atom. H(1) is bonded in a single-bond geometry to one C(1) atom. There are four inequivalent O sites. In the first O site, O(4) is bonded in a distorted single-bond geometry to two equivalent Tb(1) and one C(2) atom. In the second O site, O(1) is bonded in a distorted single-bond geometry to two equivalent Tb(1) and one C(1) atom. In the third O site, O(2) is bonded in a distorted single-bond geometry to one Tb(1) and one C(1) atom. In the fourth O site, O(3) is bonded in a distorted bent 120 degrees geometry to one Tb(1) and one C(2) atom. is represented by the CIF file [CIF]
