Infrared spectra and thermal degradation pathway of Zn(II), Cd(II) and Hg(II) alloxan diabetes adduct

Samy M. El-Megharbel , and Moamen S. Refat

Alloxan diabetes complexes with Zn(II), Cd(II) and Hg(II) metal ions have been separated in solid form and characterized on the basis of elemental analysis, molar conductivity, mid infrared spectra. The thermal decomposition the solid complexes was studied. The ligational behavior of Cd(II) and Hg(II) occurs through the oxygen in position 2 and the nitrogen in position 1. Concerning Zn(II) complex the complexation involving the carbonyl group in position 4 (or 6) can be realized through both pyrimidine nitrogen atom and one of the hydroxyl groups in position 5.
