The crystal structure described by Dy2O2CO3 crystallizes in the orthorhombic Ama2 space group. Dy(1) is bonded in a distorted body-centered cubic geometry to one O(3), three equivalent O(2), and four equivalent O(1) atoms. C(1) is bonded in a trigonal planar geometry to one O(3) and two equivalent O(2) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded to four equivalent Dy(1) atoms to form a mixture of edge and corner-sharing ODy4 tetrahedra. In the second O site, O(2) is bonded in a distorted single-bond geometry to three equivalent Dy(1) and one C(1) atom. In the third O site, O(3) is bonded in a distorted single-bond geometry to two equivalent Dy(1) and one C(1) atom. is represented by the CIF file [CIF]
