Catena-poly[[bis[5-(4-pyridyl-kappaN)-2-(2-pyridylmethylsulfanyl)-1,3,4-oxadiazole]cadmium(II)]-di-mu-thiocyanato-kappa2N:S;kappa2S:N].
The title compound, [Cd(NCS)(2)(C(13)H(10)N(4)OS)(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 pi-pi stacking interactions.
