A direct insertion probe-mass spectrometer (DIP-MS) was used for the characterization of metal complexes of L and all fragmentations and stable ions were characterized. The thermogravimetry and differential thermogravimetry (TG-DTG) plots of salen type salicylaldimine ligand and complexes showed a single step. The kinetic analysis of thermogravimetric data was performed by using the invariant kinetic parameter method (IKP). The values of the invariant activation energy, E (inv) and the invariant pre-exponential factor, A (inv), were calculated by using Coats-Redfern (CR) method. The thermal stabilities and activation energies of metal complexes of sterically hindered salen type ligand (L) were found as Co(II)> Cu(II)> Ni(II)> L and E (Cu)> E (Ni)> E (Co)> L. Also, the probabilities of decomposition functions were investigated. The diffusion functions (D (n)) are most probable for the thermal decomposition of all complexes.eninfo:eu-repo/semantics/closedAccessactivation energysterically hindered Schiff basethermal decomposition kineticthermogravimetryConference Object96126727610.1007/s10973-008-8980-8Q3WOS:0002641339000422-s2.0-62349141758Q1
