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 de ne a two-dimensional array through two different interchain pi-pi stacking interactions.
