K3SbS3 crystallizes in the cubic P2_13 space group. There are three inequivalent K sites. In the first K site, K(1) is bonded in a 6-coordinate geometry to six equivalent S(1) atoms. In the second K site, K(2) is bonded in a 6-coordinate geometry to six equivalent S(1) atoms. In the third K site, K(3) is bonded in a 6-coordinate geometry to six equivalent S(1) atoms. Sb(1) is bonded in a distorted trigonal non-coplanar geometry to three equivalent S(1) atoms. S(1) is bonded to two equivalent K(1), two equivalent K(2), two equivalent K(3), and one Sb(1) atom to form a mixture of distorted face, corner, and edge-sharing SK6Sb pentagonal bipyramids.
K3SbS3 crystallizes in the cubic P2_13 space group. There are three inequivalent K sites. In the first K site, K(1) is bonded in a 6-coordinate geometry to six equivalent S(1) atoms. There are three shorter (3.16 Å) and three longer (3.31 Å) K(1)-S(1) bond lengths. In the second K site, K(2) is bonded in a 6-coordinate geometry to six equivalent S(1) atoms. There are three shorter (3.15 Å) and three longer (3.33 Å) K(2)-S(1) bond lengths. In the third K site, K(3) is bonded in a 6-coordinate geometry to six equivalent S(1) atoms. All K(3)-S(1) bond lengths are 3.46 Å. Sb(1) is bonded in a distorted trigonal non-coplanar geometry to three equivalent S(1) atoms. All Sb(1)-S(1) bond lengths are 2.44 Å. S(1) is bonded to two equivalent K(1), two equivalent K(2), two equivalent K(3), and one Sb(1) atom to form a mixture of distorted face, corner, and edge-sharing SK6Sb pentagonal bipyramids.
