Abstract
A new Cu(II), Ni(II), Fe(III), and Sn(II) complexes of captopril (CAP) have been prepared and characterized using elemental analysis, IR spectra, molar conductance, and thermal analysis (TG). Thermal stabilities and the decomposition steps have been designed using thermogravimetric analyzer. Thermodynamic parameters were calculated from DTG curves using Coats-Redfern method.
