Streptidinium sulfate monohydrate.
In streptidinium sulfate monohydrate {systematic name: 1,1'-[(1S,3R,4S,6R)-2,4,5,6-tetrahydroxycyclohexane-1,3-diyl]diguanidinium sulfate monohydrate}, C(8)H(20)N(6)O(4)(2+).SO(4)(2-).H(2)O, at 100 (2) K, the components are arranged in double helices based on hydrogen bonds. One helix contains streptidinium cations and the other contains disordered sulfate anions and solvent water molecules. The helices are linked into a three-dimensional hydrogen-bonded network by O-H...O and N-H...O hydrogen bonds.
