Poly[[diaqua­bis­[μ-2-(4-fluoro­phen­oxy)acetato-κ²O¹:O^1′]magnesium] 0.4-hydrate]

In the title compound, {[Mg(C₈H₆FO₃)₂(H₂O)₂]·0.4H₂O}_n, slightly distorted octa­hedral MgO₆ complex units have crystallographic inversion symmetry, the coordination polyhedron comprising two trans-related water mol­ecules and four carboxyl O-atom donors, two of which are bridging. Within the two-dimensional complex polymer which is parallel to (100), coordinating water mol­ecules form inter­molecular O—H...O hydrogen bonds with carboxyl­ate and phen­oxy O-atom acceptors, as well as with the partial-occupancy solvent water mol­ecules.
