title: Poly[hexa-aqua-bis-(μ(3)-hepta-nedioato-κO:O':O'')dimagnesium].
abstract: In the title compound, [Mg(2)(C(7)H(10)O(4))(2)(H(2)O)(6)](n), the Mg(II) ion is coordinated by three aqua ligands and three O atoms from three heptanedioato ligands in a distorted octa-hedral geometry. Each heptanedioato ligand bridges three Mg atoms, generating polymeric layers parallel to the bc plane. The polymeric layers related by translation along the a axis inter-act further via O-H⋯O hydrogen bonds, which consolidate the crystal packing.
