A new two-dimensional Ag-I coordination polymer with Ag center dot center dot center dot C interactions: Thermal, fluorescence, structural and solution studies

摘要

A 2D polymer with Ag center dot center dot center dot C interactions, [Ag(mu(5)-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 0 atoms of TS-, the Ag atoms also form weak eta(l) Ag center dot center dot center dot 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. (C) 2007 Elsevier B.V.
