The adduct is tetranuclear of formula {[(CuL)3Na]CIO4}2·C8O2H8·0.5CH3CN (1). The ligand is the tetradentate di-Schiff base of 1,3-propanediamines and o-hydroxyacetophenone (H2L). The complex has been characterized by X-ray single crystal structure analysis. In the structure, the sodium cation has a six-coordinate distorted octahedral environment being bonded to six oxygen atoms from three Schiff base complexes. The complex exhibits reversible reductive (CuII/CuI; Epc, -0.914 V) and oxidative (CuII/Culll; Epa’ + 1.060 V respectively) responses in cyclic voltammetry. The generated Curspecies for the complex is unstable and undergoes disproportionation to Cu0 and Cu2+.
