A novel three‐dimensional coordination polymer, {[Pb(C 14 H 8 N 2 O 4 )(H 2 O)]·0.5C 12 H 10 N 2 } n , has been synthesized by hydrothermal reaction of Pb(OAc) 2 ·3H 2 O (OAc is acetate), 2,2′‐(diazene‐1,2‐diyl)dibenzoic acid (H 2 L ) and 1,2‐bis(pyridin‐4‐yl)ethylene (bpe). The asymmetric unit contains a crystallographically independent Pb II cation, one L 2− ligand, an aqua ligand and half a bpe molecule. Each Pb II centre is seven‐coordinated by six O atoms of bridging–chelating carboxylate groups from L 2− ligands and by one O atom from a coordinated water molecule. The Pb II cations are bridged by L 2− ligands, forming [PbO 2 ] n chains along the a axis. These chains are further connected by L 2− ligands along the b and c axes to give a three‐dimensional framework with a 4 12 6 3 topology. The channel voids are occupied by bpe molecules.
