✦ Synopsis
Á2Cl À , 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 [NÁ Á ÁCl 3.094 (5), 3.222 (5) and 3.362 (5) A Ê ]. A short contact of 3.3201 (18) A Ê is also observed between the S atom of the thiazolium cation and the chloride anion.
Experimental
DABT was prepared according to the literature procedure of Erlenmeyer (1948). The title compound was obtained from an aqueous solution as a by-product in the course of the synthesis of an Ni II complex with DABT, using NiCl 2 as a starting reagent.
