The structure described by Bi2O2CO3 crystallizes in the monoclinic Cm space group. C(1) is bonded in a trigonal planar geometry to one O(1), one O(2), and one O(4) atom. There are two inequivalent Bi sites. In the first Bi site, Bi(1) is bonded in a 6-coordinate geometry to one O(1), one O(4), and four equivalent O(3) atoms. In the second Bi site, Bi(2) is bonded in a 6-coordinate geometry to one O(1), one O(2), and four equivalent O(3) atoms. There are four inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to one C(1), one Bi(1), and one Bi(2) atom. In the second O site, O(2) is bonded in a single-bond geometry to one C(1) and one Bi(2) atom. In the third O site, O(3) is bonded to two equivalent Bi(1) and two equivalent Bi(2) atoms to form a mixture of corner and edge-sharing OBi4 tetrahedra. In the fourth O site, O(4) is bonded in a single-bond geometry to one C(1) and one Bi(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
