The thermal decomposition of pentacyanoferratecomplexes Na_x[Fe(CN)₅L]·yH₂O (L=NO⁺,N₂H₅⁺,enH⁺,NH₃,H₂O,pyridine,SO₃) in vacuum has been investigated by quadrupole mass spectrometry as well as Mssbauer spectroscopy to detect the intermediate solid products during the decomposition.The mechanism of thermal decomposition is eluci-dated and it is found that the thermal stability of these complexes was ordered in accordance with the spectrochemieal series.Kinetic study on the decomposition showed that there is a linear relationship between the decomposition activation energies and the temperatures at which the ligand L lost.
