title: Tetra-aqua-(2,2'-bipyridine-κN,N')magnesium(II) bis-(4-fluoro-benzoate).
abstract: 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) octa-hedral geometry. The Mg(II) atom is located on a twofold rotation axis and thus a cation exhibits C(2) mol-ecular 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 supra-molecular network.
