Pb4C(O2Cl3)2 crystallizes in the monoclinic P2_1/m space group. There are three inequivalent Pb sites. In the first Pb site, Pb(1) is bonded in a 2-coordinate geometry to two equivalent O(3), one Cl(1), and six equivalent Cl(4) atoms. In the second Pb site, Pb(2) is bonded in a 6-coordinate geometry to two equivalent Cl(2) and four equivalent Cl(3) atoms. In the third Pb site, Pb(3) is bonded in a 7-coordinate geometry to one O(1), two equivalent O(2), one Cl(1), one Cl(2), one Cl(3), and one Cl(4) atom. C(1) is bonded in a trigonal planar geometry to one O(1) and two equivalent O(2) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to two equivalent Pb(3) and one C(1) atom. In the second O site, O(2) is bonded in a distorted single-bond geometry to two equivalent Pb(3) and one C(1) atom. In the third O site, O(3) is bonded in a bent 120 degrees geometry to two equivalent Pb(1) atoms. There are four inequivalent Cl sites. In the first Cl site, Cl(1) is bonded in a 3-coordinate geometry to one Pb(1) and two equivalent Pb(3) atoms. In the second Cl site, Cl(2) is bonded to two equivalent Pb(2) and two equivalent Pb(3) atoms to form distorted corner-sharing ClPb4 tetrahedra. In the third Cl site, Cl(3) is bonded in a distorted T-shaped geometry to one Pb(3) and two equivalent Pb(2) atoms. In the fourth Cl site, Cl(4) is bonded to one Pb(3) and three equivalent Pb(1) atoms to form a mixture of distorted corner and edge-sharing ClPb4 tetrahedra.
