Abstract Reported herein is the investigation of the coordination chemistry of the ligand 4,5-bis(methylthio)-1,3-dithiole-2-thione (L) towards several Ag(I) salts (AgNO3, AgClO4, AgCF3SO3 and Ag-p-MeC6H4SO3) and Cu(I) (CuBr and [Cu(MeCN)4](PF6)). Six polymeric complexes have been characterised by single-crystal X-ray diffraction, FT-IR spectra and elemental analysis. This work evidences five different coordination modes for L. The sulphur-rich ligand always coordinates via the thiocarbonyl group. Additional metal–thioether interactions give rise in some cases to a polymeric structure such as in the molecular wire-like 1D polymer {[Cu(μ2-L)(MeCN)](PF6)}n. Supramolecular structures arise from a combination of metal···ligand and short S···S Van der Waals interactions. Furthermore, the emission spectra of the strongly luminescent 2D coordination polymer [Ag(μ2-L){μ2-(p-CH3C6H4SO3)}]n have been recorded.

4,5-双（甲硫基）-1,3-二硫代-2-硫酮，一种用于Cu（I）和Ag（I）配位聚合物自组装的通用富硫结构单元：二硫醚与硫代羰基键合

摘要本文报道了配体4,5-双（甲硫基）-1,3-二硫代-2-硫酮（L）对几种Ag（I）盐（AgNO3，AgClO4，AgCF3SO3和Ag- p-MeC6H4SO3）和Cu（I）（CuBr和[Cu（MeCN）4]（PF6））。通过单晶X射线衍射，FT-IR光谱和元素分析对六种聚合物配合物进行了表征。这项工作证明了L的五种不同配位模式。富硫配体始终通过硫代羰基进行配位。在某些情况下，额外的金属-硫醚相互作用会形成聚合物结构，例如在分子线状一维聚合物{[Cu（μ2-L）（MeCN）]（PF6）} n中。超分子结构由金属··配体和短S···S Van der Waals相互作用的组合产生。此外，
