In the fifth C site, C(5) is bonded in a distorted water-like geometry to one H(3), one H(4), and one S(2) atom. The C(5)-H(3) bond length is 1.10 Å. The C(5)-H(4) bond length is 1.10 Å. The C(5)-S(2) bond length is 1.82 Å. There are four inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to one C(4) atom. In the second H site, H(2) is bonded in a single-bond geometry to one C(4) atom. In the third H site, H(3) is bonded in a single-bond geometry to one C(5) atom. In the fourth H site, H(4) is bonded in a single-bond geometry to one C(5) atom. There are five inequivalent S sites. In the first S site, S(1) is bonded in a water-like geometry to one C(2) and one C(4) atom. In the second S site, S(2) is bonded in a water-like geometry to one C(1) and one C(5) atom.
