In the title compound, [Cd(C 14 H 9 O 5 ) 2 (C 12 H 10 N 2 )] n , the Cd II atom lies at a centre of symmetry and is in a highly distorted octahedral geometry. The 1,2-di-4-pyridylethylene ligand functions as a 2 -bridging ligand to form a zigzag chain. The 4,4 0 -oxydibenzoate(1À) anions protrude o

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.
