【摘要】 <正> 有机亚砜类是镧系元素的很好的配位体.S.K.Ramalingam曾研究了镧系元素高氯酸盐的二苯基亚砜(DPhSO)配合物。我们认为合成含有非配位阴离子的配合物更便于观察亚砜与镧系元素的配位作用。从这个意义上讲六氟磷酸盐比高氯酸盐更为合适,因为已经发现,在某些镧系元素亚砜配合物中,高氯酸根与镧系元素有弱配位作用。我们合成了二苯基亚砜与镧、镨、钕、钐、镱的六氟磷酸盐配合物,其组成与文献上唯一的铕所对应的配合物组成一致。同时对配合物的红外光谱、溶液中的紫外光谱以及摩尔电导进行了测定。更多还原

【Abstract】 The synthesis of the diphenyl sulfoxide complexes of crystalline lanthanide hexafluorophosphate is reported.The IR spectra,UV spectra and the molar electrolytic conductances of the complexes were determined.The compounds of the general formula [Ln(DPhSO)7](PF6 )3(where Ln=La,Pr,Nd,Sm and Yb.,DPhSO=diphenylsulfoxide) have been confirmed.The IR spectra indicate that coordination of DPhSO is through the oxygen atom and the PF6-is present in the pom-pounds as a non-coordinating anion.更多还原
