摘要
The synthesis of a new sodium perchlorate adduct (1 : 3) with a copper(II) "ligand-complex" is reported in which 2-hydroxyacetophenone acts as a guest. The adduct is tetranuclear of formula {[(CuL)(3)Na]ClO4}(2)center dot C8O2H8 center dot 0.5CH(3)CN (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 (Cu-II/Cu-I; E-pc, -0.914 V) and oxidative (Cu-II/Cu-III; E-pa, +1.060 V respectively) responses in cyclic voltammetry. The generated Cu-I species for the complex is unstable and undergoes disproportionation to Cu-0 and Cu2+.
