摘　　要：The new ligand 2-（（pyridin-4-ylmethyl）thio）-5-（quinoline-2-yl）-1,3,4-oxadiazole（L） and Ag Cl O4 produced a new coordination polymer： [（Ag2L2Cl O4）ClO 4]n（1）. The complex has been characterized by single-crystal X-ray diffraction, IR, TGA, PXRD, UV and elemental analysis. Compound 1 crystallizes in triclinic system, space group P1, with a = 8.4593（5）, b = 14.5903（9）, c = 15.7908（10） A, α = 97.357（5）, β = 99.116（5）, γ = 104.470（5）°, V = 1834.43（20） A3, Dc = 1.91056 g/cm^3, Mr = 1055.38, Z = 2, F（000） = 1048, u = 1.399 mm-1, the final S = 1.002, R = 0.049 and wR = 0.105. The compound consists of a double helix chain. The neighboring chains interact via two kinds of π-π interactions to form a two-dimensional（2D） sheet. Each sheet interacts with the neighboring sheets via π-π interactions to form an extended 3D supramolecular network.The new ligand 2-（（pyridin-4-ylmethyl）thio）-5-（quinoline-2-yl）-1,3,4-oxadiazole（L） and Ag Cl O4 produced a new coordination polymer： [（Ag2L2Cl O4）ClO 4]n（1）.
