A new manganese(II) complex [Mn 3 (bidc) 2 (C 2 O 4 )(H 2 O) 10 ] n (1) (bidc = benzimidazole-5,6-dicarboxylate) was synthesized and characterized by X-ray crystallography. X-ray diffraction shows that complex 1 has a neutral, one-dimensional (1D) brick wall chain structure. With the intramolecular and intermolecular hydrogen bonding in-

In the title complex, [Mn(C8H4O7S)(C12H8N2)2], the MnII atom is chelated by one 4-carb­oxy-2-sulfonato­benzoate anion and two phenathroline (phen) ligands in a distorted octa­hedral MnN4O2 geometry. The benzene ring of the 4-carb­oxy-2-sulfonato­benzoate anion is twisted with respect to the two phen ring systems at dihedral angles of 66.38 (9) and 53.56 (9)°. In the crystal, inter­molecular O—H⋯O and C—H⋯O hydrogen bonding links the mol­ecules into chains running parallel to [100]. Inter­molecular π–π stacking is also observed between parallel phen ring systems, the face-to-face distance being 3.432 (6) Å.
