Ln(Ⅲ)-Cu(Ⅱ)-Ln(Ⅲ)异三核配合物的合成与表征

SYNTHESIS AND CHARACTERIZATION OF NEW Ln(Ⅲ)-Cu(Ⅱ)-Ln(Ⅲ) TRINUCLEAR COMPLEXES

在甲醇体系中，合成了３种新的异三核配合物，其组成为｛Ｌｎ２（ｂｐｙ）４〔Ｃｕ（ｏｐｂａ）〕（ＣｌＯ４）２｝（ＣｌＯ４）２。其中ｏｐｂａ表示邻苯双（草胺酸根）；ｂｐｙ表示２，２′－联呲啶；Ｌｎ表示Ｙ、Ｇｄ、Ｄｙ。通过元素分析、ＩＲ、ＵＶ、ＤＴＡ－ＴＧ、摩尔电导分析等手段，表征了配合物。

Three new heterotrinuclear complexes have been synthesized and characterized,namely {Ln2(bpy)4〔Cu(opba)〕(ClO4)2}(ClO4)2,where opba denotes ophenylenebis(oxamato),bpy means 2,2′-bipyridyl and Ln represent Y,Gd,Dy.The possible structure and some properties of the complexes were studied.
