Abstract: The formation of binary and ternary complexes of glutamic acid or histidine and imipramine with Cu(II) has been examined using differential pulse polarographic technique. The reduction of both simple and mixed systems is reversible and controlled by diffusion. The obtained results reveal the formation of mixed complexes. For the system Cu-Glu-Imip, one mixed complex was formed: Cu(Glu)(Imip)₂ with stability constant log{β₁₂} = 10.51, while the system Cu-His-Imip forms two complexes Cu(His)(Imip) and Cu(His)(Imip)₂ with stabilities log{β₁₁} = 6.25 and log{β₁₂} = 8.77, respectively. These experimental values were compared with the statistical ones.
