Thermo-kinetic and Spectral Studies of Lanthanide(III) Complexes with 2-Hydroxy-l -benzylidene-2-furoyl Hydrazine

Abstract

Abstract New complexes of Ln(III) nitrate with 2-hydroxy-lbenzylidene- 2-furoyl hydrazine having the general formula [Ln(L)2NO3]H2O (where Ln = La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Er, Yb, Y; L = 2-hydroxy-l-benzylidene- 2-furoyl hydrazine) have been prepared and characterized by elemental analysis, molar conductance, magnetic measurements, electronic, infrared, 1H NMR and thermal studies. Kinetic and thermodynamic parameters were computed from the thermal decomposition data. Based on the spectral and TG studies, a coordination number of eight around the metal ions is proposed.
