Poly[[hexakis(μ-benzene-1,4-dicarboxylato)octakis(N,N-dimethylacetamide)hexamanganese(II)] monohydrate]

Abstract

In the title compound, {[Mn6(C8H4O4)6(C4H9NO)8]·H2O}n, two of the Mn atoms are six-coordinated by six O atoms from three benzene-1,4-dicarboxylate (bdc) ligands and two trans DMA (dimethylacetamide) molecules, whereas two other Mn atoms, located on inversion centers, are both in octahedral coordinations by six bdc O atoms. The discrete trinuclear manganese secondary building units (SBU) of Mn3(O2CR)6 ({–Mn—Mn—Mn-}) are linked through bdc ligands, forming a chain, while the discrete trinuclear SBU of {–Mn—Mn—Mn-} are bridged, forming another chain]. The two types of chains are linked through bdc ligands, resulting in the formation of a layer with 36 topology. Weak O—H...O and O—H...N hydrogen-bonding interactions involving the disordered water molecule (half-occupation) extend the two-dimensional layers into a three-dimensional supramolecular framework.
