Abstract
The reaction of Ni (II) acetate, Co (II) chloride and copper (II) nitrate with 4-hydroxy- 6-methyl-3-[(2E)-3-(4-(dimethylamino) phenyl)prop-2-enoyl]-2H-pyran-2-one leads to the synthesis of new complexes Ni(HL)₂, Cu(HL)₂(H₂O) and Co(HL)₂(NH₃)₄. The molecular structures of the synthesized compounds were elucidated by various physicochemical properties such as the UV-Vis, FT-IR, , and elemental analysis. Electrochemical behavior of the complexes of (Cu, Ni) has been investigated by cyclic voltammetry on glassy carbon electrode in DMF at 100 mV/s scan rate. This study indicate that the reduction process corresponding to Cu^II/Cu^I is electrochemically quasi-reversible in complex of copper, and irreversible reduction process for Ni^II/Ni^I.
