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