The asymmetric unit of the title compound, [Zn(C4H8NOS2)2(C18H12N6)]·1.5C4H8O2, comprises a Zn-containing molecule and one and a half dioxane molecules as one of the solvent molecules is located about a crystallographic inversion centre. The approximately square-pyramidal N3S2 donor set is defined by two monodentate dithiocarbamate ligands and two pyridine and one triazine N atom from the tridentate triazine ligand. Molecules are connected into a supramolecular array via O—HS and O—HN hydrogen bonds. These stack along the b axis and the solvent molecules reside in the channels thus formed.

Two pairs of independent cations and anions comprise the asymmetric unit of the title salt, C6H16NO+·C9H8N3O2S2−. The cations are virtually superimposable and each exhibits a gauche disposition of the hydroxy O and ammonium N atoms [the O—C—C—N torsion angles are 55.5 (3) and 57.5 (3)°]. Significant differences are seen in the molecular structures of the anions as seen in the S—N—C—S [1.1 (3) and 32.9 (3)°] and C—S—N—C [−69.7 (2) and 91.4 (2)°] torsion angles. Despite the variations in conformation, intramolecular hypervalent SO interactions persist in each anion [3.078 (2) and 2.8730 (19) Å]. In the crystal, supramolecular double layers are formed in the bc plane, being sustained by O—HN, N—HO and N—HN hydrogen bonding. These are connected along the a axis via C—HO interactions.
