In the structure of the title compound, [Zn(C 7 H 4 N 3 OS) 2 -(H 2 O) 4 ]Á2H 2 O, the Zn II atom, located on an inversion centre, is coordinated by the pyridyl groups of two oxadiazole ligands and four water molecules. The packing is dominated by a three-dimensional system of hydrogen bonds.

The polymeric title complex, [Zn(NO 3 ) 2 (C 24 H 20 N 8 )(H 2 O) 2 ] n , features distorted ZnN 2 O 4 octahedra with each Zn II atom being located on an inversion center. Adjacent Zn ions are doubly bridged by two equivalent 1,4-di-3-pyridyl-2,3-diaza-1,3-butadiene ligands to form linear chains.
