在干燥氮气氛中,以乙醇为溶剂制备出稀土与二乙氨基荒酸二乙铵形成的十五个配合物,测定了它们的红外及紫外光谱、热谱和电导,确定该类配合物组成为Et_2NH_2ERE(S_2CNEt_2)_4](RE=La-Lu,Y;Pm除外).镧配合物的X射线结构分析表明,在该配合物中四个二乙氨基荒酸根各通过两个硫原子与镧离子成键,从而形成八配位的十二面体阴离子,并与二乙铵阳离子形成离子缔合型的配合物分子.
Fifteen complexes of rare earth with diethylammonium dodecanoate were prepared with ethanol as solvent in a dry nitrogen atmosphere. Their IR and UV spectra, heat spectra and conductance were measured to determine their composition (Except RE = La-Lu, Y; Pm). X-ray structure analysis of lanthanum complex showed that four diethylamino-abscisic acid groups in the complex were separated by two sulfur atoms and lanthanum The ions bond to form an octa-coordinated dodecahedral anion and form ion-associative complex molecules with the diethylammonium cation.
