Description
Summary:The PbII 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 PbII atom is stereochemically active in a ψ-square-pyramidal coordination geometry in which the lone-pair electrons occupy a basal site. When three other weaker Pb...O interactions are considered, the geometry is a ψ-dodecahedron.
