摘要

The title complex, [Mn3(C11H6O3)4(C5H5N)6(H2O)2]·2H2O·2C5H5N, is a trinuclear mixed oxidation state complex of 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 MnII ion located on the inversion centre involves 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.
