In the crystal structure of the title ionic compound (C(7)H(6)NS)[AuCl(4)]·C(4)H(8)O, the AuCl(4) anion shows a typical square-planar geometry. Numerous weak C-H⋯Cl hydrogen bonds between AuCl(4) and the 1,3-benzothia-zolium units form layers comprised of 24-membered rings in which hydrogen-bonded tetra-hydro-furan (THF) solvent mol-ecules are accommodated. C-H⋯Cl inter-actions between THF and AuCl(4) from adjacent layers result in bilayers. These are further stabilized by π-π inter-actions between the thia-zole and benzene rings [centroid-centroid distance = 3.971 (3) Å], resulting in the formation of a three-dimensional supra-molecular assembly.
在标题离子化合物（C₇H₆NS）[AuCl₄]·C₄H₈O的晶体结构中，[AuCl₄]⁻阴离子呈现出典型的平面正方形几何构型。[AuCl₄]⁻与1,3-苯并噻唑鎓单元之间存在大量弱C—H⋯Cl氢键，形成了由24元环组成的层，其中容纳了通过氢键作用的四氢呋喃（THF）溶剂分子。相邻层的THF与[AuCl₄]⁻之间的C—H⋯Cl相互作用导致形成双层结构。这些双层结构通过噻唑环与苯环之间的π-π相互作用[质心-质心距离 = 3.971 (3) Å]进一步稳定，从而形成三维超分子聚集体。
