摘要
The synthesis of two heterobimetallic EDTA complexes, MgCu(EDTA).6H(2)O and ZnCu(EDTA).6H(2)O, is described. They were characterized by means of vibrational (infrared and Raman) and electronic (reflectance) spectroscopy. Several dissolution tests in 0.1 N HCl and simulated gastric juice were also performed. The results support the potential usefulness of these complexes for copper supplementation in human and veterinary medicine and to the simultaneous reinforcement of Mg(II) and Zn(II) levels.
