Six new trivalent lanthanide borate perrhenate structures─the isostructural series Ln[BO(OH)(HO)(ReO)] (Ln = Ce-Nd, Sm, Eu; ) and La[BO(OH)(HO)(ReO)] ()─have been prepared and structurally characterized. Single-crystal X-ray diffraction analysis reveals that both structures crystallize in the 2/ space group, contain 10-coordinated trivalent lanthanides in a capped triangular cupola geometry, are 3D borate framework materials, and contain either terminal () or bridging () perrhenate moieties. The presence or lack of a bridging perrhenate, along with the identity of the basal ligands, dictates how the layers are tethered together, ultimately leading to the different structures. Furthermore, the formation of is sensitive to the reaction time employed. Herein, the synthesis, structural descriptions, and spectroscopy of these trivalent lanthanide perrhenate borate complexes are presented.
六种新的三价镧系硼酸盐高铼酸盐结构——同构系列 Ln[BO(OH)(HO)(ReO)]（Ln = Ce-Nd、Sm、Eu；）和 La[BO(OH)(HO)(ReO)]（）——已经被制备并进行了结构表征。单晶 X 射线衍射分析表明，这两种结构都结晶在 2/空间群中，包含十配位的三价镧系元素，采用帽式三角锥形几何形状，是三维硼酸盐骨架材料，并含有末端（）或桥接（）高铼酸盐基团。桥接高铼酸盐的存在或缺失，以及基底配体的性质，决定了层如何连接在一起，最终导致不同的结构。此外，的形成对所使用的反应时间敏感。本文介绍了这些三价镧系高铼酸盐硼酸盐配合物的合成、结构描述和光谱学研究。
