Abstract: In the crystal structure of the title ionic compound (C₇H₆NS)[AuCl₄]·C₄H₈O, the [AuCl₄]^- anion shows a typical square-planar geometry. Numerous weak C-HCl hydrogen bonds between [AuCl₄]^- and the 1,3-benzothiazolium units form layers comprised of 24-membered rings in which hydrogen-bonded tetrahydrofuran (THF) solvent molecules are accommodated. C-HCl interactions between THF and [AuCl₄]^- from adjacent layers result in bilayers. These are further stabilized by - interactions between the thiazole and benzene rings [centroid-centroid distance = 3.971 (3) Å], resulting in the formation of a three-dimensional supramolecular assembly.
