Two copper(II) complexes, 1 and 2 with L₁ and L₂ [L₁ = 2- aminomethyl pyridine; L₂ = bis-(2-aminoethyl)amine], respectively, in degassed acetonitrile solvent, on exposure to NO gas, were found to form a thermally unstable [Cu^II鈭扤O] intermediate which then resulted in the reduction of the copper(II) centers. The formation of the [Cu^II鈭扤O] intermediate was evidenced by UV鈭抳isible, FT-IR, and EPR spectroscopic studies. The reduction of the copper(II) centers by nitric oxide afforded ligand transformation through diazotization at the primary amine coordination site, in both cases. The modified ligands, in each case, were isolated and characterized.
