钕(Ⅲ)和铒(Ⅲ)的氨基酸配合物

Nd^(3+) AND Er^(3+) COMPLEXES WITH AMINO ACID

合成和鉴别了Nd^(3+)、Er^(3+)与谷氨酸(Glu)、天冬氨酸(Asp)形成的四个新的配合物,其组成为Ln_4Glu_(11)ClO_4·8H_2O、Ln_4Asp_(11)ClO_4·8H_2O(Ln=Nd、Er),其中配体通过羧基的氧原子与镧系离子配位。并通过配合物的水溶液的f-f光谱,计算了能级、成键和强度等参数。

Four novel Nd3+ and Er3+ complexes with aspartic acid and glutamic acid have been synthesized and characterized. Their composition are Ln4Asp11ClO4·8H2O, Ln4Glu11ClO4·8H2O(Ln = Nd, Er). In these complexes artiino acid connect the Ln ions through the oxygen atoms of carboxyl groups. Absorption spectra of solution state in range 900-330 nm have been analyzed to calculate Slater-Condon, Lande, nephelauxetic effect and Judd-Ofelt intensity parameters.
