The material structure described by Pb2Cl2CO3 crystallizes in the tetragonal P4/mbm space group. Pb(1) is bonded in a 7-coordinate geometry to one O(1), three equivalent O(2), one Cl(2), and two equivalent Cl(1) atoms. C(1) is bonded in a trigonal planar geometry to one O(1) and two equivalent O(2) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to two equivalent Pb(1) and one C(1) atom. In the second O site, O(2) is bonded in a single-bond geometry to three equivalent Pb(1) and one C(1) atom. There are two inequivalent Cl sites. In the first Cl site, Cl(1) is bonded in a rectangular see-saw-like geometry to four equivalent Pb(1) atoms. In the second Cl site, Cl(2) is bonded in an L-shaped geometry to two equivalent Pb(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
