The compound described by CdCO3 crystallizes in the monoclinic P2_1/c space group. There are two inequivalent Cd sites. In the first Cd site, Cd(1) is bonded in a 6-coordinate geometry to one O(2), one O(5), two equivalent O(1), and two equivalent O(6) atoms. In the second Cd site, Cd(2) is bonded in a 6-coordinate geometry to one O(3), one O(6), two equivalent O(4), and two equivalent O(5) atoms. There are two inequivalent C sites. In the first C site, C(1) is bonded in a distorted bent 120 degrees geometry to one O(2) and one O(4) atom. In the second C site, C(2) is bonded in a distorted bent 120 degrees geometry to one O(1) and one O(3) atom. There are six inequivalent O sites. In the first O site, O(5) is bonded in a trigonal non-coplanar geometry to one Cd(1) and two equivalent Cd(2) atoms. In the second O site, O(6) is bonded in a trigonal non-coplanar geometry to one Cd(2) and two equivalent Cd(1) atoms. In the third O site, O(1) is bonded in a distorted single-bond geometry to two equivalent Cd(1) and one C(2) atom. In the fourth O site, O(2) is bonded in a distorted bent 120 degrees geometry to one Cd(1) and one C(1) atom. In the fifth O site, O(3) is bonded in a distorted bent 120 degrees geometry to one Cd(2) and one C(2) atom. In the sixth O site, O(4) is bonded in a 3-coordinate geometry to two equivalent Cd(2) and one C(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
