Abstract: As a part of our systematic study of copper(II) complexes in presence of biologically active ligands, we concluded to realize experiments with methyl- or methoxysalicylatocopper(II) complexes in presence of 2-aminomethylpyridine (ampy) ligand. This has resulted in four new complexes of the formula Cu(XSal)2(ampy) (where XSal are 3-MeSal− = 3-methylsalicylate, 4-MeSal− = 4-methylsalicylate, 5-MeSal− = 5-methylsalicylate, or 4-MeOSal− = 4-methoxylsalicylate anions). The synthesis, elemental analysis and spectral properties (EPR, electronic and infrared) are reported. The Cu(II) atom in all four complexes is probably coordinated by two nitrogen atom of the bidentate chelating ampy as well as monodentate and/or highly asymmetrically chelating salicylate anions. Based on the analyses it was concluded that the structure of these new compounds could be similar to [Cu(HCOO)2(ampy)], or [Cu(CH3COO)2(ampy)] that are reported in the literature.
Keywords: copper(II) complex, methylsalicylate anion, methoxysalicylate anion, 2-aminomethylpyridine, spectral properties
