catena-Poly[[bis­[5-(4-pyridyl-κN)-2-(2-pyridylmethyl­sulfan­yl)-1,3,4-oxa­diazole]cadmium(II)]-di-μ-thio­cyan­ato-κ²N:S;κ²S:N]

The title compound, [Cd(NCS)₂(C₁₃H₁₀N₄OS)₂]_n, contains SCN⁻ anions acting as end-to-end bridging ligands which utilize both S and N atoms to link cadmium(II) centers into one-dimensional double chains. The multidentate 5-(4-pyrid­yl)-2-(2-pyridylmethyl­sulfan­yl)-1,3,4-oxadiazole ligands behave as monodentate terminal ligands, binding metal centers only through the N atoms of the 4-pyridyl groups. Two types of eight-membered rings are formed by two SCN⁻ anions bridging Cd^II centers, viz. planar and chair conformation, which are alternately disposed along the same chain. Finally, chains define a two-dimensional array through two different inter­chain π–π stacking inter­actions.
