摘要
本文以稀土高氯酸盐RE(ClO_4)_3nH_2O(RE=La^(3+)、Ce^(3+)、Pr^(3+)、Nd^(3-)、Sm^(3-)、Eu(3+),n=6~7)与苯丁基亚砜PBSO(C_6H_5C_4H_9)在无水乙醇体系中合成出六个新配合物,并对配合物进行了元素分析,稀土离子含量测定,配体PBSO含量测定ClO_4~-含量测定、IR谱、导电、TG-DTA分析及X-射线粉末衍射。确定了配合物的组成为[RE(BPSO)_7(ClO_4)](ClO_4)_2,配位数为8,电解质类型为1:2。
in this paper the six kinds of complexes of lanthanide perchlorate with phenyl-butyl sulfoxide have been synthesized and characterized by elemental analysis , FT-IR ,X-ray powder diffraction, molar conductivities,DTA-TG analysis , From the results of elemental analysis the complex formula is found to be [RE (BPSO)_7 (ClO_4 )] (ClO_4 )_2, (RE=La-Eu, except Pm ). The IR spectra show that the PBSO coordinate with rare earth through oxygen atom and a perchlorate ion coordinates with rare earth ion through oxygen atom too. So the complexes are eight-coordinated.
