摘要
A series of lanthanide(Ⅲ) complexes of 6-methylpicolinic acid N-oxide(HL) have been synthesized and characterized by elemental analysis, molar conductance, IR, UV spectra and fluorescence spectrum measurements. The compositions of the complexes have been determined as Ln2L6. n H2O(Ln = La, Sm, Eu, Gd, Tb, Dy, n = 6; Ln = Lu, n = 9 ). The complexes with Sm, Eu, and Tb have characteristic line fluorescence emission spectra.
