The structure described by Tl3PbCl5 crystallizes in the tetragonal P4_1 space group. There are three inequivalent Tl sites. In the first Tl site, Tl(1) is bonded in a 6-coordinate geometry to one Cl(1), one Cl(3), two equivalent Cl(4), and two equivalent Cl(5) atoms. In the second Tl site, Tl(2) is bonded in a 2-coordinate geometry to one Cl(1), one Cl(3), and one Cl(4) atom. In the third Tl site, Tl(3) is bonded in a 3-coordinate geometry to one Cl(1), one Cl(3), and one Cl(5) atom. Pb(1) is bonded in a 5-coordinate geometry to one Cl(2), one Cl(4), two equivalent Cl(1), and two equivalent Cl(5) atoms. There are five inequivalent Cl sites. In the first Cl site, Cl(5) is bonded in a 4-coordinate geometry to one Tl(3), two equivalent Tl(1), and two equivalent Pb(1) atoms. In the second Cl site, Cl(1) is bonded in a 5-coordinate geometry to one Tl(1), one Tl(2), one Tl(3), and two equivalent Pb(1) atoms. In the third Cl site, Cl(2) is bonded in a single-bond geometry to one Pb(1) atom. In the fourth Cl site, Cl(3) is bonded in a distorted T-shaped geometry to one Tl(1), one Tl(2), and one Tl(3) atom. In the fifth Cl site, Cl(4) is bonded in a distorted L-shaped geometry to one Tl(2), two equivalent Tl(1), and one Pb(1) atom. is represented by the CIF file [CIF]
