Abstract
In the title complex, {[Mn3(C9H4O6)2(C9H5O6)2(C3H7NO)4(H2O)2]·4C3H7NO}n, one MnII ion sits on an inversion center, and is six-coordinated by four O atoms from four anions (monoanionic and dianionic) derived from benzene-1,3,5-tricarboxylic acid and by two dimethylformamide (DMF) molecules in a slightly distorted octahedral geometry. The other MnII ion is six-coordinated by four O atoms from four monoanionic and dianionic ligands, one DMF molecule and one water molecule in a distorted octahedral geometry. The monoanionic and dianionic ligands bridge the MnII ions, resulting in the formation of a layered structure parallel to (111) in which all of the carboxylate groups of the anionic ligands coordinate the MnII ions in a monodentate manner. Intra- and intermolecular O—H...O hydrogen bonds are present in the structure.
