Tetra­aqua­(2,2′-bipyridine-κ(2) N,N′)magnesium(II) bis­(4-fluoro­benzoate)

The title compound, [Mg(C(10)H(8)N(2))(H(2)O)(4)](C(7)H(4)FO(2))(2), consists of a bivalent [Mg(C(10)H(8)N(2))(H(2)O)(4)](2+) cation and two 4-fluorbenzoate anions. In the complex cation, the Mg(II) atom is coordinated by two N atoms from a 2,2′-bipyridine ligand and four water O atoms in a distorted MgN(2)O(4) octa­hedral geometry. The Mg(II) atom is located on a twofold rotation axis and thus a cation exhibits C (2) mol­ecular symmetry. The 2,2′-bipyridine ligands exhibit nearly perfect planarity (r.m.s. deviations = 0.0061 Å). In the crystal, O—H⋯O and C—H⋯O hydrogen bonds link the cations and anions into a three-dimensional supra­molecular network.
