Synthesis, characterization, and investigation of the thermal behavior of Cu(II) pyrazolyl complexes

This work reports the synthesis, characterization, and thermal behavior of three complexes of copper (II): [CuCl 2 (HPz) 4 ] ( 1 ), [CuCl 2 (HdmPz) 4 ] ( 2 ), and [CuCl 2 (HIPz) 4 ] ( 3 ) (HPz = pyrazole; HdmPz = 3,5-dimethylpyrazole; HIPz = 4-iodopyrazole). The compounds were characterized by eleme...

Zusammenfassung:	This work reports the synthesis, characterization, and thermal behavior of three complexes of copper (II): [CuCl 2 (HPz) 4 ] ( 1 ), [CuCl 2 (HdmPz) 4 ] ( 2 ), and [CuCl 2 (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.
