Temperature-dependent synthesis, crystal structures, characterizations, and DFT calculations of two new copper(II) complexes with p-fluorobenzoic acid and 2,2′-bipyridine ligands

Diaquabis(4,4′-bipyridine-κN)bis(2,4,5-trifluoro-3-hydroxybenzoato-κO1)manganese(II)

In the title compound, [Mn(C₇H₂F₃O₃)₂(C₁₀H₈N₂)₂(H₂O)₂], the Mn^II 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.
