| 摘要: 合成了仲丁基膦酸-2-丁基辛酯(HBO/BP)与希土(Ⅲ)(Ln=La, Gd, Ho, Y, Er, Yb)新的固体配合物，其组成为Ln(BO/BP)3，对配合物的性质进行了表征。热分析表明，在空气中，热分解分两步完成，热分解产物是Ln2P4O13。测定了配合物的红外光谱，对其主要吸收谱带进行了归属，配合物中Ln-O键具有较高的离子特性。 |

| Abstract: The new solid complexes of sec.-butyl phosphonic acid-2-butyloctyl ester (HBO/BP) with rare earths (Ln=La, Gd, Ho, Y, Er, Yb) were synthesized and their composition was identified to be Ln(BO/BP)3. The infrared spectra were measured for Ln(BO/BP)3 and principal absorption bands were assigned. The results showed that the Ln-O bands of Ln(BO/BP)3 have higher ionic characteristic. The thermal analysis of the complexes were studied in air. The thermal decomposition residues of the complexes were verified by element analysis, infrared spectra and x-ray diffraction to be Ln2P4O13 in air. |
