Abstract
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.
