合成了一系列具有开放骨架结构的稀土配合物，并用X射线衍射对其结构进行了表征。结构通式为[Ln（希达）（3）]中心点xH（2）O（Ln = La，Ce，Pr，Nd，Sm，Eu，Gd，Tb，Dy，Ho，Er，Yb; H（2）ida =亚氨基二乙酸）的聚合物呈现直径大于11埃的大六方孔道，并容纳结晶水分子。这些分子可以在加热时可逆地去除。这是第一个以ida为桥连配体的这种结构的例子。(c)2008 Elsevier B. V.保留所有权利。
A new family of lanthanide complexes with open-framework structures has been prepared and characterized by X-ray diffraction. The structure of the polymers with general formula [Ln(Hida)(3)] center dot xH(2)O (Ln = La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Yb; H(2)ida = iminodiacetic acid) presents large hexagonal channels with more than 11 angstrom diameter, and houses the crystallization water molecules. These molecules can be reversibly removed upon heating. This is the first example of this kind of structure with ida as bridging ligand. (c) 2008 Elsevier B.V. All rights reserved.
