Poly[bis(N,N-dimethylformamide-κO)(μ4-naphthalene-1,5-disulfonato)magnesium(II)]

Abstract

The structure of the title compound, [Mg(C10H6O6S2)(C3H7NO)2]n, consists of MgO6 octahedra (overline{1} symmetry) connected to naphthalene-1,5-disulfonate ligands (overline{1} symmetry) in the equatoral plane, forming a two-dimensional network propagating parallel to (010). The coordination sphere of the Mg atom is completed by the O atoms of two N,N-dimethylformamide (DMF) molecules in the axial positions. The title compound represents the first time the naphthalene-1,5-disulfonate anion is bound directly to a Mg2+ atom. Disorder over two positions was found in the DMF molecule in a 0.518 (8):0.482 (8) ratio.
