Synthesis, Crystal Structure, Photoluminescent, and Electrochemical Properties of a Novel 2-D silver(I) Coordination Polymer with 1H-1,2,4-Triazole-1-Methylene-1H-Benzimidazole-1-Acetic Acid

A new Ag(I) complex [AgL](n) (HL = 1H-1,2,4-triazole-1-methylene-1H-benzimidazole-1-acetic acid) was synthesized, and characterized by elemental analysis, IR spectra. The X-ray crystal structure of the complex was determined. The complex crystallizes in the Monoclinic system, space group p2(1)/n with a = 10.418(4) angstrom, b = 8.526(3) angstrom, c = 14.319(5) angstrom, beta = 105.700(5)degrees, V = 1224.3(8) angstrom(3), Z = 4. The complex has two-dimensional motif. The complex and free ligand display photoluminescence at room temperature. A quasi-reversible redox couple for the complex is observed.
