| Abstract: | A three-dimensional silver(I)-saccharinato (sac) coordination polymer [Ag2(μ-sac)2]n has been synthesized and characterized by elemental analysis, IR and single crystal X-ray diffraction. The silver(I) ions are doubly bridged by the imino N and carbonyl O atoms of two sac ligands, leading to a dimer [Ag2(μ-sac)2] with a very short Ag–Ag contact of 2.8622(6) Å. The dimeric units are linked by unique Ag–Csac (η1) bonds into two-dimensional ladder-like layers, which are further assembled into a three-dimensional network by weak Ag?O(sulphonyl) and π(sac)?π(sac) interactions. Complex 1 is the first example of a polymeric network involving the η1 Ag–C bonds. In addition to the new coordination mode of sac, the IR spectrum and thermal properties of the complex were discussed. |
