| Abstract: | Lanthanide complexes of 3-acetoacetyl-4-hydroxycoumar Ln(Haac)3. nH2O (Ln=La,Pr.Nd,Sm.Eu,Dy,Er, n=1 or 2) were prepared and characterized. Based on the results of IR and H-NMR, we suggest the possible coordination structure. The influence of water on the shapes of hypersensitive transitions of Nd and Er complexes indicated that the water coordinate to Nd(3 ) but not to Er(3 ) ion. |
