The crystal structure described by Nd2O2CO3 crystallizes in the orthorhombic Cmcm space group. Nd(1) is bonded in a distorted body-centered cubic geometry to one O(2), three equivalent O(1), and four equivalent O(3) atoms. C(1) is bonded in a trigonal planar geometry to one O(2) and two equivalent O(1) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to three equivalent Nd(1) and one C(1) atom. In the second O site, O(2) is bonded in a distorted single-bond geometry to two equivalent Nd(1) and one C(1) atom. In the third O site, O(3) is bonded to four equivalent Nd(1) atoms to form a mixture of corner and edge-sharing ONd4 tetrahedra. is represented by the Crystallographic Information File (CIF) [CIF]
