二价铕固态配合物的合成与性质王定博，刘建民，杨汝栋（兰州大学化学系兰州７３００００）稀土元素铕的外层电子结构为４ｆ￣７６ｓ￣２，它决定了铕除了以正常的＋３价态存在之外，还可以＋２价态的形式存在。由于（－０．３５ｖ）很低，所以Ｅｕ（Ⅱ）很容易被空气中的...
Synthesis and Properties of Bivalent Europium Solid Complexes WANG Ding-Bo, LIU Jian-Min, YANG Ru-Dong (Department of Chemistry, Lanzhou University, Lanzhou 730000) The outer electronic structure of rare earth element europium is 4f ~ 76s ~ 2, which determines the existence of europium in addition to the normal +3 valence In addition, it can be in the form of +2 valences. Because (-0.35v) is very low, Eu (II) is easily ...
