茚基及经典螯合基钕(Ⅲ)、钐(Ⅲ)化合物的合成
Synthesis of Samarium(Ⅲ) and Neodymium (Ⅲ) Complexes Involving Indenyl and Classical Chelate Ligands
【摘要】 <正> 由于“镧系收缩”的影响,轻稀土比重稀土离子具有较大的离子半径和更高的配位不饱和性,所以轻稀土化合物稳定性低,容易发生歧化反应。采用大体积配位基或螯合配合基都
【Abstract】 By the reaction of Ind3Nd or Ind3Sm (Ind=C9H7) with 8-hydroxyquinoline (H-chel1) or o-aminophenol (H-chel2), seven new complexes with mixed ligand of the gen- eral formula Ind. Ln(chel)3-n (n= 1,2; Ln=Nd, Sm: chel=chel1, chel2) have been synthe- sized. In preparing IndNd(chel2)2, a mixture of disproportionated products has been obtai- ned instead. All complexes were characterized by the elemental analysis, IR and XPS spec- troscopy.
