The material structure described by La2O2CO3 crystallizes in the orthorhombic Ama2 space group. La(1) is bonded in a distorted body-centered cubic geometry to one O(3), three equivalent O(1), and four equivalent O(2) atoms. C(1) is bonded in a trigonal planar geometry to one O(3) 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 La(1) and one C(1) atom. In the second O site, O(2) is bonded to four equivalent La(1) atoms to form a mixture of corner and edge-sharing OLa4 tetrahedra. In the third O site, O(3) is bonded in a distorted single-bond geometry to two equivalent La(1) and one C(1) atom. is represented by the CIF card [CIF]
