KCuS crystallizes in the orthorhombic Pna2_1 space group. K(1) is bonded to four equivalent S(1) atoms to form a mixture of distorted edge and corner-sharing KS4 tetrahedra. Cu(1) is bonded in a linear geometry to two equivalent S(1) atoms. S(1) is bonded to four equivalent K(1) and two equivalent Cu(1) atoms to form a mixture of distorted edge and corner-sharing SK4Cu2 octahedra. The corner-sharing octahedral tilt angles range from 0-66°.
KCuS crystallizes in the orthorhombic Pna2_1 space group. K(1) is bonded to four equivalent S(1) atoms to form a mixture of distorted edge and corner-sharing KS4 tetrahedra. There are a spread of K(1)-S(1) bond distances ranging from 3.14-3.20 Å. Cu(1) is bonded in a linear geometry to two equivalent S(1) atoms. Both Cu(1)-S(1) bond lengths are 2.14 Å. S(1) is bonded to four equivalent K(1) and two equivalent Cu(1) atoms to form a mixture of distorted edge and corner-sharing SK4Cu2 octahedra. The corner-sharing octahedral tilt angles range from 0-66°.
