| Özet |
| The asymmetric unit of the title compound, [Ni(C 6H 6N 2O) 2(H 2O) 4](C 7H 5O 3) 2·4H 2O, contains one-half of the complex cation with the Ni II ion located on an inversion center, a 3-hydroxybenzoate counter-anion and two uncoordinated water molecules. Four water O atoms in the equatorial plane around the Ni II ion [Ni - O = 2.052 (2) and 2.079 (2) Å] form a slightly distorted squareplanar arrangement, which is completed up to a distorted octahedron by the two N atoms [Ni - N = 2.075 (3) Å] from two isonicotinamide ligands. In the anion, the carboxyl-ate group is twisted from the attached benzene ring by 8.8 (3)°. In the crystal, a three-dimensional hydrogen-bonding network, formed by classical O - H⋯O and N - H⋯O hydrogen bonds, consolidates the crystal packing, which also exhibits π-π interactions between the benzene and pyridine rings, with centroid-centroid distances of 3.455 (2) and 3.621 (2) Å, respectively. |
