| 摘要: 本文报道了希土与3-乙酰乙酰基-4-羟基香豆素(H2aac)配合物的合成.其化学组成为Ln(Haac)3·nH2O(Ln为La、Pr、Nd、Eu、Gd.Dy、Er,n为1或2).基于H-NMR、IR的结果,提出了希土离子与配位体4位羟基氧与邻近羰基双齿配位结构.对Nd3+及Er3+配合物的超灵敏吸收带的形状和吸收强度等也作了讨论. |

| 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 Nd3+ but not to Er3+ ion. |
