The new ligand 2-((pyridin-4-ylmethyl)thio)-5-(quinoline-2-yl)-1,3,4-oxadiazole (L) and AgClO4 produced a new coordination polymer: [(Ag₂L₂ClO₄)ClO₄]_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) Å, α=97.357(5), β=99.116(5), γ=104.470(5)°, V=1834.43(20) Å³, D_c=1.91056 g/cm³, M_r=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.
