Poly[(μ-1H-benzimidazole-5,6-dicarboxylato)lead(II)]

Abstract

The crystal structure of the two-dimensional polymeric title compound, [Pb(C9H4N2O4)]n, comprises one crystallo­graphic­ally independent PbII atom and one fully deprotonated 1H-benzimidazole-5,6-dicarboxyl­ate (H2 L) ligand. The PbII atom is seven-coordinated by six O atoms and one N atom from the H2 L ligands, giving a capped octa­hedral coordination geometry. The structure is a layered two-dimensional coordination polymer extending parallel to (100) with N—H⋯O hydrogen bonds inter­actions between the layers, stabilizing the crystal structure.
