Abstract: | The title complex {[AgL]CIO_4}_n (L = 2,5-bis(3-pyridinylmethylthio)-1,3,4-thiadiazole) was synthesized by the reaction of Ag(Ⅰ) salt and a novel flexible ligand L. Its structure was determined by X-ray crystallography with the following data: monoelinie, space group P2_1/n, α =16.5068(13), b = 7.6548(4), c = 16.5521(13)(A), β=115.119(3)°, V= 1893.7(2) (A)~3, Z = 4, D_c =1.893 g/cm~3, μ = 1.565 mm~(-1), F(000) = 1072, C_(14)H_(12)AgC1N_4O_4S_3, M_r= 539.78, T = 293(2) K, S=1.067, the final R = 0.0342 and wR = 0.0870. The silver ion in the complex is in a trigonal coordination geometry to link three different L. Meanwhile, each L connects three different silver ions by its N coordination sites to form a two-dimensional layer structure. |
