The material structure described by Rb5(Pb3Cl8)2 crystallizes in the tetragonal P4/mbm space group. There are three inequivalent Rb sites. In the first Rb site, Rb(1) is bonded in a 10-coordinate geometry to two equivalent Cl(2), four equivalent Cl(1), and four equivalent Cl(3) atoms. In the second Rb site, Rb(2) is bonded in a 9-coordinate geometry to two equivalent Cl(2), three equivalent Cl(4), and four equivalent Cl(1) atoms. In the third Rb site, Rb(3) is bonded in a distorted body-centered cubic geometry to eight equivalent Cl(1) atoms. There are two inequivalent Pb sites. In the first Pb site, Pb(1) is bonded in a 4-coordinate geometry to four equivalent Cl(1) atoms. In the second Pb site, Pb(2) is bonded to one Cl(2), one Cl(4), two equivalent Cl(1), and two equivalent Cl(3) atoms to form a mixture of distorted edge and corner-sharing PbCl6 pentagonal pyramids. There are four inequivalent Cl sites. In the first Cl site, Cl(2) is bonded to two equivalent Rb(1), two equivalent Rb(2), and two equivalent Pb(2) atoms to form edge-sharing ClRb4Pb2 octahedra. In the second Cl site, Cl(3) is bonded in a distorted see-saw-like geometry to two equivalent Rb(1) and two equivalent Pb(2) atoms. In the third Cl site, Cl(4) is bonded in a 5-coordinate geometry to three equivalent Rb(2) and two equivalent Pb(2) atoms. In the fourth Cl site, Cl(1) is bonded in a 5-coordinate geometry to one Rb(1), one Rb(2), one Rb(3), one Pb(1), and one Pb(2) atom. is represented by the CIF file [CIF]
