摘要
A series of new complexes of formula Ln(acac)_s(Ph_3PO)_3 (where Ln^(3+)=Nd^(3+), Sm^(3+), Eu^(3+), Tb^(3+), Ho^(3+)) have been prepared and characterized. The coordination of two ligands with lanthanide ions are studied by IR spectra, ~1H, ^(13)C, ^(31)P-NMR and metal-ligand charge tranafer tranaition is also discussed via electronic adaorption and luminescence spectroscopy.
