Abstract: The Pb^II atom in the polymeric title compound, [Pb(C₈H₄O₄)(C₁₂H₆N₂O₂)]_n, is chelated by the N-heterocycle, and adjacent atoms are bridged by rigid terephthalate dianions into a linear chain. The Pb^II atom is stereochemically active in a -square-pyramidal coordination geometry in which the lone-pair electrons occupy a basal site. When three other weaker PbO interactions are considered, the geometry is a -dodecahedron.
