Abstract

The title compound, C16H12NOSSe(+)·HSO4 (-), was obtained from a mixture of 3-(4-meth-oxy-phen-yl)[1,3]selenazolo[2,3-b][1,3]benzo-thia-zol-4-ium chloride and potassium hydrogen sulfate. In the cation, the benzene ring is twisted by 71.62 (7)° from the tricycle mean plane. In the crystal, O-H⋯O hydrogen bonds link the anions into chains along [100]. The anions in adjacent chains are linked via weak C-H⋯O hydrogen bonds. The crystal packing exhibits short inter-molecular contacts between the chalcogen unit and the O atoms: Se⋯O(anion) 2.713 (3), Se⋯O(cation) 2.987 (3) and S⋯O(anion) 2.958 (3) Å.
