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.
