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) ?, α = 97.357(5), β = 99.116(5), γ = 104.470(5)°, V = 1834.43(20) ?3, Dc = 1.91056 g/cm3, 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.
