The new vic-dioxime ligand 2 (LH(4)) carrying a 14-membered N2O2 macrocycle has been prepared. Mononuclear complex (LH(3))(2)Ni, trinuclear complexes (LH)(2)Cu-3, (LH)(2)Co-3. (LH)(2)Pd-3, and (LH)(2)Co-3(py)(3)Cl-3, dinuclear complex (LH(3))(2)-(UO2)(2)(OH)(2), and pentanuclear complex [L(2)Cu(5)(phen)(2)]-(NO3)(2) have been synthesized from LH(4). The electrochemical properties of tri- and pentanuclear complexes were investigated by cyclic voltammetry. For (LH)(2)Cu-3 two reduction waves appeared at 0.215 and -0.870 V. [L(2)Cu(5)(phen)(2)](No-3)(2) exhibited four reduction waves at 0.200, -0.025, -0.670, and -1.170 V.
