Crystal structure of poly[(N,N-dimethylacetamide-κO)(μ4-5-methylisophthalato-κ5O:O,O′:O′′:O′′′)manganese(II)]

Abstract

The title compound, poly[(N,N-dimethylacetamide-κO)(μ4-5-methylisophthalato-κ5O,O′:O′,O′′:O′′)manganese(II)], [Mn(C9H6O4)(C3H7NO)]n, was obtained from a mixture containing MnCl2·4H2O and 5-methylisophthalic acid in N,N-dimethylacetamide solution. The Mn2+ ion is coordinated by five O atoms from four bridging 5-methylisophthalate ligands and one O atom from one N,N-dimethylacetamide ligand, defining a considerably distorted coordination polyhedron with one very long Mn—O bond of 2.623 (2) Å. The Mn2+ ions are joined by carboxylate groups, forming rod-shaped secondary building units along the a axis. The rods are further connected by 5-methylisophthalate ligands to form the pcu (primitive cubic net) structure.
