The compound described by Pb3O2Cl2 crystallizes in the orthorhombic Pnma space group. There are three inequivalent Pb sites. In the first Pb site, Pb(1) is bonded in a 4-coordinate geometry to four equivalent O(1) atoms. In the second Pb site, Pb(2) is bonded in a 2-coordinate geometry to two equivalent O(1), one Cl(1), and one Cl(2) atom. In the third Pb site, Pb(3) is bonded in a 2-coordinate geometry to two equivalent O(1) and two equivalent Cl(2) atoms. O(1) is bonded to one Pb(2), one Pb(3), and two equivalent Pb(1) atoms to form a mixture of corner and edge-sharing OPb4 tetrahedra. There are two inequivalent Cl sites. In the first Cl site, Cl(1) is bonded in a single-bond geometry to one Pb(2) atom. In the second Cl site, Cl(2) is bonded in a 3-coordinate geometry to one Pb(2) and two equivalent Pb(3) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
