【Abstract】 A new Ag^Ⅰ complex based on a flexible trithioether ligand （L, namely 1,3,5-tri（phenylthio-methyl）-2,4,6-trimethylbenzene）, {[Ag₃（L）₂（ClO₄）₂]（ClO₄）}_∞ （1）, has been synthesized and structurally characterized by means of elemental analysis, infrared （IR） spectra and X-ray diffraction. Complex 1 crystallizes in monoclinic crystal system, C2/c space group with a=3.493 1（7） nm, b=2.158 4（8） nm, （c=）2.878 2（4） nm, β=123.688（10）^o, V=18.056（3） nm³, Z=8. There are three crystallographically independent Ag^Ⅰ ions in the asymmetric unit of complex 1, one of which is four-coordinated and the other two exhibit the linear coordination modes. Each ligand links three adjacent Ag^Ⅰ ions with its three sulfur donors, resulting in a nearly hexagonal 48-membered macrocyclic repeating unit that consists of six metal ions and six ligands. The most notable feature of 1 resides in the formation an infinite honeycomb-like two-dimensional （2-D） （6,3） coordination network with such repeating units.更多还原
