SYNTHESES AND SPECTROSCOPIC PROPERTIES OF LANTHANIDE COMPLEXES, Ln(acac)_3(Ph_3PO)_3

摘要

A series of new complexes of formula Ln（acac）_s（Ph₃PO）₃ (where Ln3+=Nd3+, Sm3+, Eu3+, Tb3+, Ho3+) have been prepared and characterized. The coordination of two ligands with lanthanide ions are studied by IR spectra, 1H, 13C, 31P-NMR and metal-ligand charge tranafer tranaition is also discussed via electronic adaorption and luminescence spectroscopy.
