摘要：

Cobalt(iii) complexes with different 4,6-di-tert-butyl-N-(aryl)-o-iminobenzosemiquinone ligands were synthesized. Four-, five-, or six-coordinate cobalt(iii) derivatives can be prepared using various starting metal compounds (CoCl2 center dot 6H(2)O, (acac)(2)Co center dot 2H(2)O) and varying substituents in the N-aryl moiety of the organic ligand. The structures of five synthesized compounds were determined by X-ray diffraction. The electronic and spin states of the five-coordinate cobalt(iii) complexes were studied in detail by DFT quantum chemical calculations.
