HSCs crystallizes in the tetragonal I4/m space group. There are two inequivalent Cs sites. In the first Cs site, Cs(1) is bonded in a 8-coordinate geometry to four equivalent H(1) and four equivalent S(1) atoms. In the second Cs site, Cs(2) is bonded in a 8-coordinate geometry to four equivalent H(1) and four equivalent S(1) atoms. H(1) is bonded in a distorted single-bond geometry to two equivalent Cs(1), two equivalent Cs(2), and one S(1) atom. S(1) is bonded in a single-bond geometry to two equivalent Cs(1), two equivalent Cs(2), and one H(1) atom.
HSCs crystallizes in the tetragonal I4/m space group. There are two inequivalent Cs sites. In the first Cs site, Cs(1) is bonded in a 8-coordinate geometry to four equivalent H(1) and four equivalent S(1) atoms. All Cs(1)-H(1) bond lengths are 3.22 Å. All Cs(1)-S(1) bond lengths are 3.69 Å. In the second Cs site, Cs(2) is bonded in a 8-coordinate geometry to four equivalent H(1) and four equivalent S(1) atoms. All Cs(2)-H(1) bond lengths are 3.25 Å. All Cs(2)-S(1) bond lengths are 3.68 Å. H(1) is bonded in a distorted single-bond geometry to two equivalent Cs(1), two equivalent Cs(2), and one S(1) atom. The H(1)-S(1) bond length is 1.35 Å. S(1) is bonded in a single-bond geometry to two equivalent Cs(1), two equivalent Cs(2), and one H(1) atom.
