The structure described by KSn2Cl5 crystallizes in the tetragonal I4/mcm space group. K(1) is bonded in a distorted q6 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 K(1) and four equivalent Sn(1) atoms to form corner-sharing ClK2Sn4 octahedra. The corner-sharing octahedral tilt angles range from 0-33°. In the second Cl site, Cl(1) is bonded in a distorted trigonal non-coplanar geometry to two equivalent K(1) and one Sn(1) atom. is represented by the CIF file [CIF]
