Diaqua­bis­(N,N′-diethyl­nicotinamide-κN (1))bis­(4-fluoro­benzoato-κO)copper(II)

The asymmetric unit of the title mononuclear Cu(II) complex, [Cu(C(7)H(4)FO(2))(2)(C(10)H(14)N(2)O)(2)(H(2)O)(2)], contains one-half of the mol­ecule. The Cu(II) ion is located on an inversion centre, and is coordinated by two N atoms from two diethyl­nicotinamide ligands, two O atoms from two 4-fluoro­benzoate (PFB) ligands and two water mol­ecules in a distorted octa­hedral geometry. In the PFB ligand, the carboxyl­ate group is twisted at an angle of 2.10 (14)° from the attached benzene ring. In the crystal structure, inter­molecular O—H⋯O hydrogen bonds link mol­ecules related by translation along the a axis into chains. Weak inter­molecular C—H⋯O hydrogen bonds and π–π inter­actions between the pyridine rings of neighbouring mol­ecules [centroid-to-centroid distance = 3.571 (2) Å] further consolidate the crystal packing.
