A new two-dimensional AgI coordination polymer with Ag⋯C interactions: Thermal, fluorescence, structural and solution studies

A 2D polymer with Ag⋯C interactions, [Ag(μ5-TS)]n (1) [TS− = toluene-4-sulfonate], has been synthesized and characterized and its structure was determined by X-ray crystallography. In addition to coordination of the O atoms of TS−, the Ag atoms also form weak η1 Ag⋯C interactions. The thermal stability of 1 was studied by thermal gravimetric (TG) and differential thermal analyses (DTA). The ligand and compound 1 are luminescent in DMF, with emission maxima at 358 and 335, respectively. Solution studies of complex 1 were done in DMF and in CH3CN.
