K2CuS(O2Cl)2 crystallizes in the orthorhombic Pnma space group. There are two inequivalent K sites. In the first K site, K(1) is bonded in a 8-coordinate geometry to one O(1), one O(3), two equivalent O(2), one Cl(2), and three equivalent Cl(1) atoms. In the second K site, K(2) is bonded in a 6-coordinate geometry to four equivalent O(2), one Cl(1), and one Cl(2) atom. Cu(1) is bonded in a distorted rectangular see-saw-like geometry to one O(1), one O(3), one Cl(1), and one Cl(2) atom. S(1) is bonded in a tetrahedral geometry to one O(1), one O(3), and two equivalent O(2) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to one K(1), one Cu(1), and one S(1) atom. In the second O site, O(2) is bonded in a distorted single-bond geometry to one K(1), two equivalent K(2), and one S(1) atom. In the third O site, O(3) is bonded in a 3-coordinate geometry to one K(1), one Cu(1), and one S(1) atom. There are two inequivalent Cl sites. In the first Cl site, Cl(1) is bonded to one K(2), three equivalent K(1), and one Cu(1) atom to form a mixture of distorted corner and edge-sharing ClK4Cu trigonal bipyramids. In the second Cl site, Cl(2) is bonded in a 1-coordinate geometry to one K(1), one K(2), and one Cu(1) atom.
