| Özet |
| The asymmetric unit of the title compound, [Co(C 6H 6N 2O) 2(H 2O) 4](C 7H 5O 3) 2·4H 2O, contains one-half of the complex cation with the Co 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 Co II ion [Co - O = 2.0593 (16) and 2.1118 (16) Å] form a slightly distorted square-planar arrangement, and the distorted octahedral geometry is completed by the two N atoms [Co - N = 2.1306 (18) Å] from two isonicotinamide ligands. In the anion, the carboxylate group is twisted from the attached benzene ring at 8.84 (17)°. 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 exhibits π-π interactions between the benzene and pyridine rings, with centroid-centroid distances of 3.458 (1) and 3.606 (1) Å, respectively. |
