Abstract: The title complex, [Mn₃(C₁₁H₆O₃)₄(C₅H₅N)₆(H₂O)₂]·2H₂O·2C₅H₅N, is a trinuclear mixed oxidation state complex of $\\overline1$ symmetry. The three Mn atoms are six-coordinated in the shape of distorted octahedra, each coordinated with an O₄N₂ 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 O₄N₂ set of donor atoms orginating from the organic ligands. Intramolecular C-H [pi] interactions between neighbouring pyridine ligands stabilize this arrangement. A two-dimensional network parallel to (001) is formed by intermolecular O-HO hydrogen bonds.
