Synthesis and characterization of an anion triazole framework containing μ 3-Cl and μ 2-Cl bridges

Abstract

Using 3,5-dimethyl-4-amino-1,2,4-triazole (L) and corresponding Ag(I), K(I) salts under ammonia solution and hydrothermal conditions, a triazole–silver(I)–potassium(I) complex {K[Ag2L2(μ 3-Cl)(μ 2-Cl)2]} n (1) has been isolated. In 1, μ 3-Cl, μ 2-Cl and L bridge AgI ions forming a rare 1-D [Ag2L2(μ 3-Cl)(μ 2-Cl)2]− anion while K+ cations are located between neighboring anion chains. Strong solid-state fluorescence spectrum of 1 was also investigated showing that the excited peak is located at 320 nm while the maximum emission peak is located at 440 nm.
