Abstract: In the title compound, [Mn(C₄H₂O₄)(C₇H₆N₂)₃]_n, maleate dianions bridge neighbouring Mn^II ions to form helical polymeric chains. The Mn ion assumes a distorted octahedral coordination geometry, formed by two maleate and three benzimidazole ligands. One maleate carboxyl group chelates to the Mn atom with longer Mn-O bond distances while the other carboxyl group coordinates in a monodentate manner to the Mn atom.
