The effect of substituted pyridines bases upon the coordination of thiosaccharinate (tsac, C₇H₄NO₂S₂⁻ 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)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 μ₂-S mode and in the 4-MeOpy complex it was bound in a μ₃-S form both resulting in polymeric chains. In the 4-Mepy complex the anion was bound in a μ₂-S,N head to head mode and in the quinoline complex in a μ₂-S,N head to tail mode, both showing dinuclear arrangements.
