Effect of coordination of lead(II) nitrilo-tris-methylenephosphonate complexes on their thermal behavior in the compact state and in the chemisorbed layers on steel surface according to thermogravimetry and X-ray photoelectron spectroscopy in situ

Resumo

The thermal decomposition of two lead(II) complexes with the same ligand, nitrilo-tris-methy-lenephosphonic acid N(CH₂PO₃)₃H₆, but with different coordination modes, in the compact state and as chemisorbed layers on a steel surface, was studied by TGA and X-ray photoelectron spectroscopy. Using these methods, the thermal decomposition was conducted in the spectrometer chamber with simultaneous recording of the electronic spectra in situ. The differences in the thermochemical behavior of lead(II) complexes were elucidated.
