The effect of substituted pyridines bases upon the coordination of thiosaccharinate (tsac, C7H4NO2S27H4NO2S2 in ternary silver complexes is analyzed. Four crystalline silver-substituted pyridine complexes with tsac as a coordinating counter anion, [Ag(tsac)(3-methylpyridine)2]n, [Ag2(tsac)2(4-methylpyridine)]n, [Ag2(tsac)2in ternary silver complexes is analyzed. Four crystalline silver-substituted pyridine complexes with tsac as a coordinating counter anion, [Ag(tsac)(3-methylpyridine)2]n, [Ag2(tsac)2(4-methylpyridine)]n, [Ag2(tsac)22]n, [Ag2(tsac)2(4-methylpyridine)]n, [Ag2(tsac)2 (quinoline)2] and [Ag(tsac)(4-methyloxypyridine)]n were synthesized and characterized by means of spectroscopic (IR and Raman, UV–Vis, and 1H and 13C NMR) and X-ray diffraction techniques. The thiosaccharinate anion showed its versatility coordinating to the metal in each complex by a different way. In the 3-Mepy complex it was coordinated in a l2-S mode and in the 4-MeOpy complex it was bound in a l3-S form both resulting in polymeric chains. In the 4-Mepy complex the anion was bound in a l2-S,N head to head mode and in the quinoline complex in a l2-S,N head to tail mode, both showing dinuclear arrangements.2] and [Ag(tsac)(4-methyloxypyridine)]n were synthesized and characterized by means of spectroscopic (IR and Raman, UV–Vis, and 1H and 13C NMR) and X-ray diffraction techniques.
