Hexaaquamagnesium(II) bis(pyridinium-2,6-dicarboxylate)
Abstract
In the title compound, [Mg(H2O)6](C7H4NO4)2, a single six-coordinate Mg2+ cation (site symmetry 2/m) is bonded to six water molecules in a distorted octahedral geometry. The crystal packing between the complex cation and the zwitterionic organic cation (m symmetry) is stabilized by intermolecular O—H...O hydrogen bonds and weak intermolecular C—H...O interactions.
