A three‐dimensional PbII coordination framework: poly[[μ4‐(E)‐2,2′‐(diazene‐1,2‐diyl)dibenzoato]dimethanollead(II)]

In the title coordination polymer, Pb(C₁₄H₈N₂O₄)(CH₃OH)₂]_n, the asymmetric unit contains half of a Pb^II cation, half of a 2,2′‐(diazene‐1,2‐diyl)dibenzoate dianionic ligand (denoted L^2?) and one methanol ligand. Each Pb^II centre is eight‐coordinated by six O atoms of chelating/bridging carboxylate groups from four L^2? ligands and two O atoms from two terminal methanol ligands, forming a distorted dodecahedron. The PbL₂(MeOH)₂] subunits are interlinked via the sharing of two carboxylate O atoms to form a one‐dimensional PbL₂(MeOH)₂]_n chain. Adjacent chains are further connected by L^2? ligands, giving rise to a two‐dimensional layer, and these layers are bridged by L^2? linkers to afford a three‐dimensional framework with a 4¹²6³ topology.
