Diaqua­Bis­(N,N′-Diethyl­Nicotinamide-Κn1)Bis­(4-Fluoro­Benzoato-Κo)Copper(Ii)

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—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.
