The compound described by Gd(CO3)2 crystallizes in the orthorhombic Amm2 space group. Gd(1) is bonded in a 9-coordinate geometry to one O(1), one O(2), one O(5), two equivalent O(4), and four equivalent O(3) atoms. There are three inequivalent C sites. In the first C site, C(1) is bonded in a distorted bent 120 degrees geometry to two equivalent O(1) atoms. In the second C site, C(2) is bonded in a distorted bent 120 degrees geometry to two equivalent O(2) atoms. In the third C site, C(3) is bonded in a trigonal planar geometry to one O(4) and two equivalent O(3) atoms. There are five inequivalent O sites. In the first O site, O(1) is bonded in a bent 120 degrees geometry to one Gd(1) and one C(1) atom. In the second O site, O(2) is bonded in a bent 120 degrees geometry to one Gd(1) and one C(2) atom. In the third O site, O(3) is bonded in a 3-coordinate geometry to two equivalent Gd(1) and one C(3) atom. In the fourth O site, O(4) is bonded in a distorted single-bond geometry to two equivalent Gd(1) and one C(3) atom. In the fifth O site, O(5) is bonded in a single-bond geometry to one Gd(1) atom. is represented by the CIF file [CIF]
