Properties of N,N-Bis[2-(isonicotinoyloxy)ethyl]-p-toluenesulfonamide.Structures of Its Silver(I)Complexes via Anion Effects

摘要

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 C1(V)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.
