The title complex, [Mn(3)(C(11)H(6)O(3))(4)(C(5)H(5)N)(6)(H(2)O)(2)]·2H(2)O·2C(5)H(5)N, is a trinuclear mixed oxidation state complex of [Image: see text] symmetry. The three Mn atoms are six-coordinated in the shape of distorted octa­hedra, each coordinated with an O(4)N(2) set of donor atoms, where the ligands exhibit mono- and bidentate modes. However, the coordination of the Mn(II) ion located on the inversion centre involves water mol­ecules at two coordination sites, whereas that of the two symmetry-related Mn(III) ions involves an O(4)N(2) set of donor atoms orginating from the organic ligands. Intramolecular C—H⋯π interactions between neighbouring pyridine ligands stabilize this arrangement. A two-dimensional network parallel to (001) is formed by inter­molecular O—H⋯O hydrogen bonds.
