| Özet |
| The asymmetric unit of the crystal structure of the title complex, [Co(C6H6N2O)2(H2O) 4](C8H5O3)2· 2H2O, contains one-half of the complex cation with the Co II ion 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 CoII ion form a slightly distorted square-planar arrangement with an average Co - O bond length of 2.086 Å; the slightly distorted octa-hedral coordination is completed by the two N atoms of the isonicotinamide (INA) ligands at a slightly longer distance [2.1603 (14) Å] in the axial positions. The dihedral angle between the carboxyl-ate group and the attached benzene ring is 5.93 (13)°, while the pyridine and benzene rings are oriented at a dihedral angle of 3.09 (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 = 3.758 (1) Å] may further stabilize the crystal structure. © Ḧkelek et al. 2009. |
