Abstract

<abstract abstract-type="main" xml:lang="en"> <title> <x xml:space="preserve">Abstract</x> </title> <p>In the title coordination polymer, [Pb(C₁₄H₈N₂O₄)(CH₃OH)₂]_{<italic>n</italic>}, the asymmetric unit contains half of a Pb^II cation, half of a 2, 2′‐(diazene‐1, 2‐diyl)dibenzoate dianionic ligand (denoted <italic>L</italic>²⁻) and one methanol ligand. Each Pb^II centre is eight‐coordinated by six O atoms of chelating/bridging carboxylate groups from four <italic>L</italic>²⁻ ligands and two O atoms from two terminal methanol ligands, forming a distorted dodecahedron. The [Pb<italic>L</italic>₂(MeOH)₂] subunits are interlinked <italic>via</italic> the sharing of two carboxylate O atoms to form a one‐dimensional [Pb<italic>L</italic>₂(MeOH)₂]_{<italic>n</italic>} chain. Adjacent chains are further connected by <italic>L</italic>²⁻ ligands, giving rise to a two‐dimensional layer, and these layers are bridged by <italic>L</italic>²⁻ linkers to afford a three‐dimensional framework with a 4¹²6³ topology.</p> </abstract>
