The material described by K2Sn3(SbS5)2 crystallizes in the monoclinic P2_1/c space group. K(1) is bonded in a 5-coordinate geometry to one S(3), one S(4), one S(5), and two equivalent S(1) atoms. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded to two equivalent S(1), two equivalent S(2), and two equivalent S(3) atoms to form edge-sharing SnS6 octahedra. In the second Sn site, Sn(2) is bonded to one S(2), one S(3), one S(4), and two equivalent S(5) atoms to form distorted SnS5 trigonal bipyramids that share  an edgeedge with one Sn(1)S6 octahedra and  an edgeedge with one Sn(2)S5 trigonal bipyramid. Sb(1) is bonded in a distorted T-shaped geometry to one S(1), one S(2), and one S(4) atom. There are five inequivalent S sites. In the first S site, S(1) is bonded to two equivalent K(1), one Sn(1), and one Sb(1) atom to form corner-sharing SK2SnSb trigonal pyramids. In the second S site, S(2) is bonded in a 3-coordinate geometry to one Sn(1), one Sn(2), and one Sb(1) atom. In the third S site, S(3) is bonded in a 3-coordinate geometry to one K(1), one Sn(1), and one Sn(2) atom. In the fourth S site, S(4) is bonded in a 3-coordinate geometry to one K(1), one Sn(2), and one Sb(1) atom. In the fifth S site, S(5) is bonded in a 3-coordinate geometry to one K(1) and two equivalent Sn(2) atoms. is represented by the CIF file [CIF]
