The structure described by KCu4S3 crystallizes in the tetragonal P4/mmm space group. K(1) is bonded in a body-centered cubic geometry to eight equivalent S(2) atoms. Cu(1) is bonded to two equivalent S(1) and two equivalent S(2) atoms to form a mixture of corner and edge-sharing CuS4 tetrahedra. There are two inequivalent S sites. In the first S site, S(1) is bonded in a body-centered cubic geometry to eight equivalent Cu(1) atoms. In the second S site, S(2) is bonded in a 8-coordinate geometry to four equivalent K(1) and four equivalent Cu(1) atoms. is represented by the CIF file [CIF]
