Bis­(4-fluoro­benzoato)-κ(2) O,O′;κO-(4-fluoro­benzoic acid-κO)bis­(nico­tinamide-κN (1))copper(II)

In the title Cu(II) complex, [Cu(C(7)H(4)FO(2))(2)(C(7)H(5)FO(2))(C(6)H(6)N(2)O)(2)], the Cu(II) cation is coordinated by two N atoms of two nicotinamide (NA) ligands, and by four O atoms from two 4-fluoro­benzoate (PFB) anions and one 4-fluoro­benzoic acid (PFBA) mol­ecule, in a distorted octa­hedral geometry. In the mol­ecule, two Cu—O bond lengths are significantly longer than the other two. The dihedral angles between the carboxyl­ate groups and the adjacent benzene rings are 11.08 (14), 7.62 (13) and 5.73 (11)°, while the benzene rings are oriented at dihedral angles of 15.62 (6), 33.71 (8) and 26.60 (8)°. In the crystal structure, extensive N—H⋯O, C—H⋯F and C—H⋯O hydrogen bonds link the mol­ecules into a three-dimensional network. π–π contacts between the benzene rings [centroid-to-centroid distances = 3.5517 (15), 3.8456 (14) and 3.9265 (13) Å] further stabilize the crystal structure.
