The compound described by KPb2Cl5 crystallizes in the orthorhombic Pna2_1 space group. K(1) is bonded in a 8-coordinate geometry to one Cl(3), one Cl(4), two equivalent Cl(1), two equivalent Cl(2), and two equivalent Cl(5) atoms. There are two inequivalent Pb sites. In the first Pb site, Pb(1) is bonded in a distorted pentagonal planar geometry to one Cl(1), one Cl(2), one Cl(3), one Cl(4), and one Cl(5) atom. In the second Pb site, Pb(2) is bonded to one Cl(1), one Cl(2), one Cl(5), two equivalent Cl(3), and two equivalent Cl(4) atoms to form distorted edge-sharing PbCl7 pentagonal bipyramids. There are five inequivalent Cl sites. In the first Cl site, Cl(1) is bonded in a distorted rectangular see-saw-like geometry to two equivalent K(1), one Pb(1), and one Pb(2) atom.
