Abstract
In the title compound, [Mn(C7H2F3O3)2(C10H8N2)2(H2O)2], the MnII ion, situated on a centre of inversion, has a distorted octahedral 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-hydroxybenzoate ligands and two water molecules. Intermolecular O—H⋯N hydrogen bonds link the molecules into a chain along the a axis. Interactions between neighboring chains occur through O—H⋯O hydrogen bonds, which link the chains into a two-dimensional supramolecular network parallel to the ac plane. In addition, O—H⋯O hydrogen bonds between the water molecules and carboxylate groups also exist in the the crystal structure.
