In the title molecule, C10H16O3S4, a short intramolecular SO(=C) distance [2.726 (2) Å] indicates the presence of a nonbonding attractive interaction. In the crystal, molecules are linked into centrosymmetric dimers via weak intermolecular C—HO and SS [3.405 (3) Å] interactions. These dimers are linked by further weak C—HO interactions into columns along the a axis.

In the structure of the title salt C12H11N2S+·I−, the methylsulfanyl group of the cation is nearly coplanar with the perimidine rings, as indicated by the C—S—C—N torsion angles of 2.9 (5) and −177.2 (3)°, respectively. The (S)C—N bond lengths in the heterocyclic ring are approximately equal [1.325 (5) and 1.326 (6) Å] suggesting a degree of delocalization. In the crystal, cations and anions are linked via two discrete N—HI hydrogen bonds, forming chains along the b axis.
