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 Hoodie 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 MnII ion located on the inversion centre involves MANGO SHAMPOO water molecules at two coordination sites, whereas that of the two symmetry-related MnIII ions involves an O4N2 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.
