Abstract: The asymmetric unit of the title mononuclear CuII complex, [Cu(C7H4FO2)2(C10H14N2O)2(H2O)2], contains one-half of the molecule. The CuII 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-HO hydrogen bonds link molecules related by translation along the a axis into chains. Weak intermolecular C-HO hydrogen bonds and - interactions between the pyridine rings of neighbouring molecules [centroid-to-centroid distance = 3.571 (2) Å] further consolidate the crystal packing.
