چکیده    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.
