摘要：

Zinc(II) complexes 2, 3, and 5 with redox-amphoteric o-indophenol ligands were prepared. The molecular structures of tetracoordinate complex 2 and hexacoordinate complex 3 were determined by single-crystal X-ray diffraction. The antioxidant properties of indophenols and their complexes were studied by cyclic voltammetry (CVA) and EPR spectroscopy. Complexation of indophenols increases the oxidation potentials by more than 0.84 V and leads to the formation of stable metal-containing radicals.
