Abstract
This work reports the synthesis, characterization, and thermal behavior of three complexes of copper (II): [CuCl2(HPz)4] (1), [CuCl2(HdmPz)4] (2), and [CuCl2(HIPz)4] (3) (HPz = pyrazole; HdmPz = 3,5-dimethylpyrazole; HIPz = 4-iodopyrazole). The compounds were characterized by elemental analysis, infrared spectroscopy, and UV–Vis measurements. The thermal study of the compounds showed that the ligands are eliminated in 2–4 stages, yielding CuO as final residue.
