The compound described by K3(CuS)4 crystallizes in the orthorhombic Pbam space group. There are two inequivalent K sites. In the first K site, K(1) is bonded in a 6-coordinate geometry to two equivalent S(2) and four equivalent S(1) atoms. In the second K site, K(2) is bonded in a 6-coordinate geometry to two equivalent S(1) and four equivalent S(2) atoms. There are two inequivalent Cu sites. In the first Cu site, Cu(1) is bonded in a trigonal planar geometry to one S(1) and two equivalent S(2) atoms. In the second Cu site, Cu(2) is bonded in a distorted trigonal planar geometry to one S(2) and two equivalent S(1) atoms. There are two inequivalent S sites. In the first S site, S(1) is bonded in a 8-coordinate geometry to one K(2), four equivalent K(1), one Cu(1), and two equivalent Cu(2) atoms. In the second S site, S(2) is bonded in a 7-coordinate geometry to two equivalent K(1), two equivalent K(2), one Cu(2), and two equivalent Cu(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
