Síntese, caracterização espectroscópica e estrutural de um complexo de cobre (II) com ligante diimina derivado da aminoguanidina

Abstract

Coordination chemistry is involved with many different areas of research . Coordination compounds are relevant in catalysis, bioinorganic and medicinal chemistry. Complexes with N -donor ligands have been extensively described in the literature . However, aminoguanidine derivatives in comparison with other nitrogenous compounds has been rarely reported in coordination chemistry. In the present work, is described the synthesis of a complex of copper (II) with diimine ligand aminoguanidine derivative. The complex and ligand were characterized by infrared spectroscopy and UV-vis spectroscopy. The actual percentages of carbon, hydrogen and nitrogen were obtained by CHN elemental analysis. The structure of the complex has been obtained by x-ray diffraction crystallography, showing a distorted pyramidal geometry, where copper is coordinated to four nitrogen atoms (the base of the pyramid) and a chlorine atom in the apical position.
