Differences in thermal decomposition of Ag(I), Mn(II), Fe(II) and Fe(III) complexes of cyclic dithiocarbamates

The thermal decomposition of pyrrolidinedithiocarbamate (Pyr) and piperidin edithiocarbamate (Pip) complexes of Ag(I), Mn(II), Fe(II) and Fe(III) have been investigated by thermogravimetry and differential scanning calorimetry . The decomposition intermediates and final products were identified from t heir X-ray diffraction patterns. Changes in their IR spectra were correlate d with their thermogravimetric profiles. The hydrated compounds decomposed without loss of water and oxides were detected as the final decomposition p roducts even in nitrogen atmosphere. (C) 2001 Elsevier Science B.V. All rig hts reserved.
