title: Poly[(μ-1H-benzimidazole-5,6-dicarboxyl-ato)lead(II)].
abstract: The crystal structure of the two-dimensional polymeric title compound, [Pb(C(9)H(4)N(2)O(4))](n), comprises one crystallo-graphic-ally independent Pb(II) atom and one fully deprotonated 1H-benzimidazole-5,6-dicarboxyl-ate (H(2)L) ligand. The Pb(II) atom is seven-coordinated by six O atoms and one N atom from the H(2)L ligands, giving a capped octa-hedral coordination geometry. The structure is a layered two-dimensional coordination polymer extending parallel to (100) with N-H⋯O hydrogen bonds inter-actions between the layers, stabilizing the crystal structure.
