| Özet |
| In the title Cu II complex, [Cu(C 7H 4FO 2) 2(C 7H 5FO 2)(C 6H 6N 2O) 2], the Cu II cation is coordinated by two N atoms of two nicotinamide (NA) ligands, and by four O atoms from two 4-fluoro-benzoate (PFB) anions and one 4-fluoro-benzoic acid (PFBA) mol-ecule, in a distorted octa-hedral geometry. In the mol-ecule, two Cu - O bond lengths are significantly longer than the other two. The dihedral angles between the carboxyl-ate 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 mol-ecules 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. © Necefoǧlu et al. 2011. |
