The compound described by K2CdSnS4 crystallizes in the monoclinic C2/c space group. There are two inequivalent K sites. In the first K site, K(1) is bonded in a 6-coordinate geometry to one S(1), one S(2), one S(3), one S(5), and two equivalent S(4) atoms. In the second K site, K(2) is bonded in a 6-coordinate geometry to one S(1), one S(2), one S(3), one S(5), and two equivalent S(4) atoms. Cd(1) is bonded to one S(1), one S(2), one S(3), and one S(4) atom to form CdS4 tetrahedra that share  a cornercorner with one Cd(1)S4 tetrahedra and corners with three equivalent Sn(1)S4 tetrahedra. Sn(1) is bonded to one S(1), one S(2), one S(4), and one S(5) atom to form SnS4 tetrahedra that share  a cornercorner with one Sn(1)S4 tetrahedra and corners with three equivalent Cd(1)S4 tetrahedra. There are five inequivalent S sites. In the first S site, S(1) is bonded in a rectangular see-saw-like geometry to one K(1), one K(2), one Cd(1), and one Sn(1) atom. In the second S site, S(2) is bonded in a distorted rectangular see-saw-like geometry to one K(1), one K(2), one Cd(1), and one Sn(1) atom. In the third S site, S(3) is bonded in a 6-coordinate geometry to two equivalent K(1), two equivalent K(2), and two equivalent Cd(1) atoms. In the fourth S site, S(4) is bonded in a 6-coordinate geometry to two equivalent K(1), two equivalent K(2), one Cd(1), and one Sn(1) atom. In the fifth S site, S(5) is bonded in a 6-coordinate geometry to two equivalent K(1), two equivalent K(2), and two equivalent Sn(1) atoms. is represented by the CIF file [CIF]
