S is red selenium-like structured and crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of four heptasulfur molecules. There are seven inequivalent S sites. In the first S site, S(1) is bonded in a water-like geometry to one S(2) and one S(4) atom. In the second S site, S(2) is bonded in a water-like geometry to one S(1) and one S(6) atom. In the third S site, S(3) is bonded in a water-like geometry to one S(5) and one S(7) atom. In the fourth S site, S(4) is bonded in a water-like geometry to one S(1) and one S(7) atom. In the fifth S site, S(5) is bonded in a water-like geometry to one S(3) and one S(6) atom. In the sixth S site, S(6) is bonded in a water-like geometry to one S(2) and one S(5) atom. In the seventh S site, S(7) is bonded in a water-like geometry to one S(3) and one S(4) atom.
