Abstract

The new vic‐dioxime ligand 2 (LH₄) carrying a 14‐membered N₂O₂ macrocycle has been prepared. Mononuclear complex (LH₃)₂Ni, trinuclear complexes (LH)₂Cu₃, (LH)₂Co₃, (LH)₂‐Pd₃, and (LH)₂Co₃(py)₃Cl₃, dinuclear complex (LH₃)₂‐(UO₂)₂(OH)₂, and pentanuclear complex [L₂Cu₅(phen)₂]‐(NO₃)₂ have been synthesized from LH₄. The electrochemical properties of tri‐ and pentanuclear complexes were investigated by cyclic voltammetry. For (LH)₂Cu₃ two reduction waves appeared at 0.215 and ‐0.870 V. [L₂Cu₅(phen)₂](NO₃)₂ exhibited four reduction waves at 0.200, ‐0.025, ‐0.670, and ‐1.170 V.
