摘要

通过对钆衍生物的x射线结构研究,发现了一种新的草酸镧系化合物[Ln(H2O)3]2(C2O4)3,其Ln = Eu−Dy。与已知的镧系草酸盐不同的是,这种结构不含沸石水,但它仍然是分层的,基本的组成部分被保留了下来。沸石水的损失导致了网络单元的一些变形。

Synthèse et structure d’un oxalate de gadolinium ne contenant pas de molécule d’eau libre, [Gd(H2O)3]2(C2O4)3

A new family of lanthanide oxalate, [Ln(H2O)3]2(C2O4)3 with Ln = Eu−Dy, has been characterized through the X-ray structural study of the gadolinium derivative. In contrast to the lanthanide oxalates already known, this structure is free of zeolitic water but it remains layered and the basic building blocks are preserved. The loss of zeolitic water leads to some deformations of the network units.
