In the title compound, [Mg2(C7H10O4)2(H2O)6]n, the MgII ion is coordinated by three aqua ligands and three O atoms from three heptanedioato ligands in a distorted octahedral 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 interact further via O—H⋯O hydrogen bonds, which consolidate the crystal packing.
