CsPb2Cl5 crystallizes in the tetragonal I4/mcm space group. Cs(1) is bonded in a 10-coordinate geometry to two equivalent Cl(1) and eight equivalent Cl(2) atoms. Pb(1) is bonded in a 8-coordinate geometry to two equivalent Cl(1) and six equivalent Cl(2) atoms. There are two inequivalent Cl sites. In the first Cl site, Cl(1) is bonded to two equivalent Cs(1) and four equivalent Pb(1) atoms to form corner-sharing ClCs2Pb4 octahedra. The corner-sharing octahedral tilt angles range from 0-37°. In the second Cl site, Cl(2) is bonded in a 5-coordinate geometry to two equivalent Cs(1) and three equivalent Pb(1) atoms.
CsPb2Cl5 crystallizes in the tetragonal I4/mcm space group. Cs(1) is bonded in a 10-coordinate geometry to two equivalent Cl(1) and eight equivalent Cl(2) atoms. Both Cs(1)-Cl(1) bond lengths are 3.75 Å. All Cs(1)-Cl(2) bond lengths are 3.62 Å. Pb(1) is bonded in a 8-coordinate geometry to two equivalent Cl(1) and six equivalent Cl(2) atoms. Both Pb(1)-Cl(1) bond lengths are 3.04 Å. There are two shorter (2.77 Å) and four longer (3.21 Å) Pb(1)-Cl(2) bond lengths. There are two inequivalent Cl sites. In the first Cl site, Cl(1) is bonded to two equivalent Cs(1) and four equivalent Pb(1) atoms to form corner-sharing ClCs2Pb4 octahedra. The corner-sharing octahedral tilt angles range from 0-37°. In the second Cl site, Cl(2) is bonded in a 5-coordinate geometry to two equivalent Cs(1) and three equivalent Pb(1) atoms.
