【Abstract】 Five lanthanide complexes are synthesized from Ln(NO3)3·6H2O(Ln=Sm,Gd,Dy,Ho,Tm) and a schiff base,2-(2-hydroxyphenyl)imino-3-(4-hydroxyphenyl)-propanic acid.The latter is derived from salicylaldehyde and L-tyrosine.These complexes are characterized with element analysis,infrared spectroscopy,ultraviolet spectroscopy,molar conductivity measurements,thermogravimetric analysis),and differential thermal analysis.The stoichiometry is deduced to be \(C2H5OH)(NO3),and the possible structure is proposed.The thermal decomposition reaction kinetics of Dy complex is studied by thermogravimetry.更多还原
