CsSn2Cl5 crystallizes in the tetragonal I4/mcm space group. Cs(1) is bonded in a 10-coordinate geometry to two equivalent Cl(2) and eight equivalent Cl(1) atoms. Sn(1) is bonded in a 4-coordinate geometry to two equivalent Cl(1) and two equivalent Cl(2) atoms. There are two inequivalent Cl sites. In the first Cl site, Cl(2) is bonded to two equivalent Cs(1) and four equivalent Sn(1) atoms to form corner-sharing ClCs2Sn4 octahedra. The corner-sharing octahedral tilt angles range from 0-30°. In the second Cl site, Cl(1) is bonded in a distorted trigonal non-coplanar geometry to two equivalent Cs(1) and one Sn(1) atom.
