| Abstract: | The coordination behavior of copper(II) with tricarballylic acid (H3TCA) and imidazole (Imz) is described. Speciation in aqueous solution has been determined at 25 °C and 0.15 M NaCl ionic strength by potentiometric measurements and EPR characterization of the species. Two new compounds CuTCAH · 3H2O and CuTCAHImz · 2H2O were obtained and characterized by elemental analysis diffuse reflectance, FTIR (Fourier transform infrared spectroscopy), EPR and thermal behavior. Their in vitro superoxide dismutase-mimetic activities have been tested. |
