The material described by CuPb8As2(O3Cl)3Cl2 crystallizes in the monoclinic C2/m space group. The structure consists of eight hydrochloric acid atoms inside a CuPb8As2(O3Cl)3 framework. In the CuPb8As2(O3Cl)3 framework, Cu(1) is bonded to two equivalent As(1) and two equivalent Cl(3) atoms to form distorted CuAs2Cl2 tetrahedra that share corners with two equivalent O(3)AsPb3 tetrahedra and  an edgeedge with one Cu(1)As2Cl2 tetrahedra. There are five inequivalent Pb sites. In the first Pb site, Pb(1) is bonded in a 4-coordinate geometry to one O(1), one O(2), one O(4), and one O(5) atom. In the second Pb site, Pb(2) is bonded in a 3-coordinate geometry to one O(1) and two equivalent O(4) atoms. In the third Pb site, Pb(3) is bonded in a 4-coordinate geometry to one O(4), one O(5), and two equivalent O(3) atoms. In the fourth Pb site, Pb(4) is bonded in a 3-coordinate geometry to one O(3), two equivalent O(5), and one Cl(1) atom. In the fifth Pb site, Pb(5) is bonded in a 3-coordinate geometry to one O(1) and two equivalent O(2) atoms. As(1) is bonded in a 4-coordinate geometry to one Cu(1), one O(2), one O(3), and one O(4) atom. There are five inequivalent O sites. In the first O site, O(1) is bonded to one Pb(2), one Pb(5), and two equivalent Pb(1) atoms to form corner-sharing OPb4 tetrahedra. In the second O site, O(2) is bonded in a 1-coordinate geometry to one Pb(1), one Pb(5), and one As(1) atom. In the third O site, O(3) is bonded to one Pb(4), two equivalent Pb(3), and one As(1) atom to form distorted OAsPb3 tetrahedra that share  a cornercorner with one Cu(1)As2Cl2 tetrahedra, corners with two equivalent O(5)Pb4 tetrahedra,  an edgeedge with one O(3)AsPb3 tetrahedra, and  an edgeedge with one O(5)Pb4 tetrahedra. In the fourth O site, O(4) is bonded in a 4-coordinate geometry to one Pb(1), one Pb(2), one Pb(3), and one As(1) atom. In the fifth O site, O(5) is bonded to one Pb(1), one Pb(3), and two equivalent Pb(4) atoms to form OPb4 tetrahedra that share  a cornercorner with one O(1)Pb4 tetrahedra, corners with two equivalent O(3)AsPb3 tetrahedra,  an edgeedge with one O(3)AsPb3 tetrahedra, and  an edgeedge with one O(5)Pb4 tetrahedra. There are two inequivalent Cl sites. In the first Cl site, Cl(1) is bonded in a distorted single-bond geometry to one Pb(4) atom. In the second Cl site, Cl(3) is bonded in an L-shaped geometry to two equivalent Cu(1) atoms. is represented by the CIF file [CIF]
