Abstract
 N,N-Bis[2-(isonicotinoyloxy)ethyl]-p-toluenesulfonamide (L) as a new ligand was synthesized and characterized. The photoluminescence spectrum of L shows a bright blue emission at 417 nm. The slow diffusion of an organic solution of L into an aqueous solution of AgX (X = BF4? and ClO4?) affords a metallacyclodimer consisting of [Ag(L)]2X2. Each L acts as a bidentate fashion, and thus connects two Ag(I) ions to form the metallacyclodimer. For [Ag(L)]2(BF4)2, the BF4? anions are positioned around Ag(I) ion, and for [Ag(L)]2- (ClO4)2, the ClO4? anions are positioned at the metallacyclodimeric ring. The delicate difference between both structures in solid state can be explained by the coordinating ability of anions.
