In poly[[μ 2 ‐1,2‐bis(pyridin‐4‐yl)ethene‐κ 2 N : N ′][μ 2 ‐2,2′‐(diazenediyl)dibenzoato‐κ 3 O , O ′: O ′′]cadmium(II)], [Cd(C 14 H 8 N 2 O 4 )(C 12 H 10 N 2 )] n , the asymmetric unit contains one Cd II cation, one 2,2′‐(diazenediyl)dibenzoate anion (denoted L 2− ) and one 1,2‐bis(pyridin‐4‐yl)ethene ligand (denoted bpe). Each Cd II centre is six‐coordinated by four O atoms of bridging/chelating carboxylate groups from three L 2− ligands and by two N atoms from two bpe ligands, forming a distorted octahedron. The Cd II cations are bridged by L 2− and bpe ligands to give a two‐dimensional (4,4) layer. The layers are interlinked through bridging carboxylate O atoms from L 2− ligands, generating a two‐dimensional bilayered structure with a 3 6 4 13 6 2 topology. The bilayered structures are further extended to form a three‐dimensional supramolecular architecture via a combination of hydrogen‐bonding and aromatic stacking interactions.
