Abstract :
A thermoanalytical study of unusual adrenaline coordination compounds with the divalent transition-metal ions Co(II), Ni(II) and Cu(II) is reported. The precipitated compounds were characterized by elemental analysis and by thermogravimetric (TG) analysis coupled to FTIR spectroscopy to analyze the evolved gases and make consistent the proposed decomposition steps. The complexes were obtained with metal/ligand molar ratios of 1:1 (base unit, only for the copper), 1:3 and 1:5.
