Abstract: The asymmetric unit of the title compound, [Cu(C7H4FO2)2(C6H6N2O)2(H2O)]·0.5C6H6N2O·3H2O, contains two aquabis(4-fluorobenzoato)bis(nicotinamide)copper(II) molecules, one nicotinamide solvent molecule and six water molecules. The CuII ion is coordinated by two O atoms from two 4-fluorobenzoate ligands, two N atoms from two nicotinamide ligands and one water O atom in a distorted square-pyramidal geometry. In the crystal, O-H...O, O-H...N and N-H...O hydrogen bonds consolidate the crystal packing, which also exhibits [pi]-[pi] interactions between the aromatic rings [centroid-centroid distances 3.692 (2)-3.794 (2) Å].
