Redox-active metal(II) complexes of sterically hindered phenolic ligands: Antibacterial activity and reduction of cytochrome c. Part III. Copper(II) complexes of cycloaminomethyl derivatives of o-diphenols

Synthesis and characterization of Cu(II) complexes of cycloaminomethyl derivatives of o-diphenols. The phenolic ligands coordinate in their monoanionic forms. The coordination core of these complexes is a square planar chromophore [CuO2N2]. The compounds with the highest reducing ability (determined electrochemically) are characterized by the highest rates of cytochrome c reduction; Gram-positive bacteria are more sensitive to these compounds.
