Resumo: Two new copper(II) complexes, [Cu4Cl6O(C6H11 N3)4] (1) and [CuBr2(C6H11N3)4] (2), were synthesized and characterized by single crystal X-ray diffractometry, IR spectroscopy and elemental analysis. They were used as bulk modifiers for the fabrication of two carbon paste electrodes (Cu-CPE): 1-CPE and 2-CPE. They had similar electrochemical behaviors characterized by cyclic voltammetry and good electrocatalytic activities toward the reduction of hydrogen peroxide and trichloroacetic acid. The detection limits, linear calibration ranges and sensitivities were respectively 0.01 μmol L-1, 0.02 to 0.20 μmol L-1 and 98.80 μA μmol L-1 for hydrogen peroxide detection, and 0.01 μmol L-1, 0.02 to 0.20 μmol L-1 and 80.05 μA μmol L-1 for trichloroacetic acid detection.
