Coordination compounds – preparation, structures, properties and applications

The 6-oxonicotinate salts of a one-dimensional cationic nickel(II) and cobalt(II) coordination compounds with 4, 4’-bipyridine were prepared hydrothermally by reactions of cobalt(II) or nickel(II) nitrate hexahydrate with 6-hydroxynicotinic acid and 4, 4’-bipyridine. Our investigation is focused on the preparation of coordination compounds and their application in electroanalysis, based on previous knowledge about the excellent electrocatalytic performance of this type of compound. The highly oxidative species present in these materials, Ni(II)/Ni(III) or Co(II)/Co(III) represent a catalytically active centre towards short chains or small molecules. The focus of this paper was to investigate the electrochemical properties, determine the origin of electrochemical differences in the isostructural system and investigate potential applications for catalytic oxidation of methanol. The Co-BPY/6-Onic and Ni-BPY/6-Onic ({; ; [Co(4, 4’-bpy)(H2O)4](6-Onic)2×2H2O}; ; n and {; ; [Ni(4, 4’-bpy)(H2O)4](6-Onic)2×2H2O}; ; n) as isostructural coordination compounds exhibit different electrochemical behaviour, as observed by cyclic voltammetry, which can be attributed to the nature of the metal ions. The results indicated that the electrode modified with Ni-BPY/6-Onic show stability and reproducibility in 0.1 M NaOH, and oxidation current increases with the increase of methanol concentration. On the other hand, electrode modified with Co-BPY/6-Onic is non-reproducible and cannot be used for electroanalytical purposes. The GCE modified with Ni-BPY/6-Onic was successfully applied in the determination of methanol.
