Abstract: The title compound, C₆H₈N₄S₂²⁺·2Cl^-, includes a trans, planar bithiazole moiety occupying a special position on a crystallographic inversion centre. Both symmetry-independent N atoms participate in hydrogen-bonded links with the chloride anion [NCl 3.094 (5), 3.222 (5) and 3.362 (5) Å]. A short contact of 3.3201 (18) Å is also observed between the S atom of the thiazolium cation and the chloride anion.
