| Popis: | The reaction of AgNO3 with the ligand 2,2′,2′′,2′′′-{[pyrazine-2,3,5,6-tetrayltetrakis(methylene)]tetrakis(sulfanediyl)}tetraacetic acid in the presence of a potassium acetate buffer lead to the formation of a silver(I)–potassium–organic framework, poly[dipotassium [(μ6-2,2′,2′′,2′′′-{[pyrazine-2,3,5,6-tetrayltetrakis(methylene)]tetrakis(sulfanediyl)}tetraacetato)disilver(I)] 5.2-hydrate], {K2[Ag2(C16H16N2O8S4)]·5.2H2O}n, (I). The asymmetric unit is composed of half a binuclear silver complex located about a center of symmetry, a potassium cation and 2.6 disordered water molecules. The whole binuclear silver complex is generated by inversion symmetry with the pyrazine ring being located about an inversion centre. The ligand coordinates in a bis-tetradentate manner. The binuclear silver complex anions are linked via bridging Ag...S...Ag zigzag bonds, forming a network lying parallel to the bc plane. The networks are linked by Ocarboxylate...K+...Ocarboxylate bridging bonds to form a framework. The disordered water molecules are present near to the K+ cations. |
