The H(7)-O(4) bond length is 1.67 Å. The H(7)-O(6) bond length is 1.00 Å. S(1) is bonded in a distorted trigonal non-coplanar geometry to one O(3), one O(4), and one O(5) atom. The S(1)-O(3) bond length is 1.46 Å. The S(1)-O(4) bond length is 1.48 Å. The S(1)-O(5) bond length is 1.48 Å. There are six inequivalent O sites. In the first O site, O(4) is bonded in a water-like geometry to one H(7) and one S(1) atom. In the second O site, O(5) is bonded in a bent 120 degrees geometry to one H(6) and one S(1) atom.
