Aqueous Synthesis and Thermal Decomposition Behavior of Rare Earth Complexes with o-Carboxylbenzaldehyde-2-Pyrroleformylhydrazone Ligand

Abstract:

Thirteen novel complexeswere synthesized using this method, by employing the designed ligand o-carboxylbenzaldehyde-2-pyrroleformylhydrazone (H₂L). Elemental analysis, molar conductivity,Fourier transform infrared (FTIR) spectracharacterizations show that the composition formula of the complexes is RE(HL)(H₂L)•2H2O (where RE=La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Yb and Y). The thermal decomposition of the thirteen complexes was studied by _{Subscript text}TG-DTG analysis and their apparent activation energies (E) were calculated by Kissinger’s and Flynn-Wall-Ozawa’s methods.
