Özet
The asymmetric unit of the title complex, [Ni(C6H 6N2O)2(H2O)4](C 8H5O3)2·2H2O, contains one-half of the complex cation with the NiII atom located on an inversion center, a 4-formyl-benzoate (FB) counter-anion and an uncoordinated water mol-ecule. The four O atoms in the equatorial plane around the Ni atom form a slightly distorted square-planar arrangement and the slightly distorted octa-hedral coordination is completed by the two N atoms of the isonicotinamide (INA) ligands at a sligthly longer distance in the axial positions. The dihedral angle between the carboxyl-ate group and the attached benzene ring is 8.14 (11)°, while the pyridine and benzene rings are oriented at a dihedral angle of 3.46 (6)°. In the crystal structure, O - H⋯O, N - H⋯O and C - H⋯O hydrogen bonds link the molecules into a three-dimensional network. π-π Contacts between the benzene and pyridine rings [centroid-centroid distance = 3.751 (1) Å] may further stabilize the crystal structure. © Ḧkelek et al. 2009.
