| 摘要: |
| 在乙醇水溶液体系中合成6种稀土-二氯苯氧乙酸配合物,用化学分析方法确定其通式为RE(DCP)3、RE(DCP)3 phen、RE(DCP)2 hq(RE=La、Y;DCP=2,4-二氯苯氧乙酸根;phen=邻菲罗啉;hq=8-羟基喹啉)。6种配合物均溶于二甲基甲酰胺(DMF)、二甲基亚砜,但不溶于水、乙醇、丙酮。RE(DCP)3为白色粉末,RE(DCP)3.phen为粉红色粉末,La(DCP)2.hq为黄色粉末,Y(DCP)2.hq为淡绿色粉末。摩尔电导7.44~33.61s·cm2·mol-1。对配合物进行紫外光谱、红外光谱、热分析,表明同类配合物的紫外光谱、红外光谱均相似,游离配体及配合物在紫外光区均产生π-π*跃迁吸收峰;配合物的热稳定性高于游离配体。 |

| Abstract: |
| Six solid complexes of rare earth with 2,4-dicholophenoxyacetic acid are synthesized,and their compositions are proved to be RE(DCP)3、RE(DCP)2 phen、RE(DCP)2 hq(RE=La、Y;DCP=2,4-dichlorophenoxyacetic acid;phen=1,10-phenanthroline;hq=8-hydroxyquinoline) by the chemical analysis. Their structure characteristics were studied by means of IR spectrum、UV spectrum、DTA analysis. These six complexes are soluble in dimethylformamide(DMF) and dimethyl sulfoxide,but insoluble in water,ethanol and acetone. RE(DCP)3 is the white powder,RE(DCP)3. phen the pale red powder,La(DCP)2. hq the yellow powder,Y(DCP)2. hq the pale green powder. The molar conductivity ranges from 7.44 s·cm2·mol-1 to 33.61s·cm2·mol-1. There are the same UV and IR spectra in the same group complexes. The free ligands and complexes have the π-π* peak in UV spectra. The complexes are more stable than free ligands in thermal condition. |
