title: Diaqua-bis-(4,4'-bipyridine-κN)bis-(2,4,5-trifluoro-3-hy-droxy-benzoato-κO)manganese(II).
abstract: In the title compound, [Mn(C(7)H(2)F(3)O(3))(2)(C(10)H(8)N(2))(2)(H(2)O)(2)], the Mn(II) ion, situated on a centre of inversion, has a distorted octa-hedral coordination geometry and is coordinated by two N atoms from two 4,4'-bipyridine ligands, two O atoms from two 2,4,5-trifluoro-3-hy-droxy-benzoate ligands and two water mol-ecules. Inter-molecular O-H⋯N hydrogen bonds link the mol-ecules into a chain along the a axis. Inter-actions between neighboring chains occur through O-H⋯O hydrogen bonds, which link the chains into a two-dimensional supra-molecular network parallel to the  ac plane. In addition, O-H⋯O hydrogen bonds between the water mol-ecules and carboxyl-ate groups also exist in the the crystal structure.
