Poly[[diaqua­bis­(μ₃-3,5-dicarb­oxy­benzo­ato-κ³O¹:O³:O⁵)bis­(μ₃-5-carb­oxy­ben­zene-1,3-dicarboxyl­ato-κ³O¹:O³:O⁵)tetrakis(methylformamide-κO)tri­man­ganese(II)] dimethyl­formamide tetra­solvate]

In the title complex, {[Mn₃(C₉H₄O₆)₂(C₉H₅O₆)₂(C₃H₇NO)₄(H₂O)₂]·4C₃H₇NO}_n, one Mn^II 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 Mn^II 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 Mn^II 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 Mn^II ions in a monodentate manner. Intra- and inter­molecular O—H...O hydrogen bonds are present in the structure.
