Some cobalt(III) complexes with a potentially tetradentate unsymmetrical NNOS Schiff base ligand have been synthesized and characterized using IR, 1 HNMR, UV-Vis spectroscopy and elemental analysis. The equilibrium constants were measured spectrophotometrically for 1:1 adduct formation of the cobalt(III) complexes with some cyclic amines in acetonitrile as solvent at constant ionic strength (I = 0.1 M NaClO 4 ), and at various temperatures. In addition, the ground state geometries of the complexes were optimized using density functional theory (DFT) at B3LYP/6-311G** level. Binding energy, thermodynamic parameters, structural parameters and electronic structures of complexes are investigated. The theoretical investigations were done for comparing with the experimental results. Our comparison between the computational and experimental results revealed that the cobalt(III) complexation process is spontaneous, exothermic and entropically unfavorable.

This chapter is an update of a recent review on the acid–base chemistry and solvation properties of metal phenolates. After a brief introduction on the physicochemical properties of metal phenolates, the interaction between phenolate ligands and metal Lewis acids is discussed. Examples of solvent effects on the acid–base properties, structure, and chemical reactivity are presented. Furthermore, the interaction of multidentate phenolic ligands and metal cations is highlighted because of their relevance in transition‐metal coordination chemistry, catalyst development, metalloenzyme mimicry, cytotoxicity, and magnetic properties.
