The material described by Gd(OH)CO3 crystallizes in the orthorhombic P2_12_12_1 space group. Gd(1) is bonded in a 10-coordinate geometry to two equivalent O(3), two equivalent O(4), three equivalent O(1), and three equivalent O(2) atoms. C(1) is bonded in a trigonal planar geometry to one O(1), one O(2), and one O(4) atom. H(1) is bonded in a single-bond geometry to one O(3) atom. There are four inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to three equivalent Gd(1) and one C(1) atom. In the second O site, O(2) is bonded in a distorted single-bond geometry to three equivalent Gd(1) and one C(1) atom. In the third O site, O(3) is bonded in a distorted single-bond geometry to two equivalent Gd(1) and one H(1) atom. In the fourth O site, O(4) is bonded in a distorted single-bond geometry to two equivalent Gd(1) and one C(1) atom. is represented by the CIF file [CIF]
