摘要:
It is well known that lanthanides is one of the most difficult groups of elements to be separated in the periodical table because of the so-called lanthanide contraction. Among lanthanides,the 4f orbital of gadolinium(Ⅲ) is half-filled——4f7,such a stable configuration leads to the effects from coordination field weaker on gadolinium than that on the adjacent lanthanides, and the stabilities of gadolinium(Ⅲ) complexes somewhat lower than those of europium(Ⅲ) in some cases.
