Abstract: The asymmetric unit of the title compound, [Pb(C₇H₇N₂O₂)₂]_n, consists of a Pb^II ion and two 3,5-diaminobenzoate anions. The Pb^II ion is coordinated by one N and five O atoms from four different 3,5-diaminobenzoate ligands in a hemidirected polyhedral geometry, with a Pb-N distance of 2.625 (5) Å and Pb-O distances in the range 2.354-2.719 Å. The ₂-bridging 3,5-diaminobenzoate anions connect the Pb^II ions into a two-dimensional layer. These two-dimensional layers are linked further by N-HN and N-HO intermolecular hydrogen-bond interactions, forming an extensive three-dimensional network.
