Abstract

Seven isomorphous 1D chain Ln3+ complexes Ln(BTA)(HCOO)(H2O)3 (Ln = Pr (1), Gd (2), Eu (3), Tb (4) Dy (5), Er (6) and Yb (7)), and two formate coordinating and bridging 3D Ln3+ complexes Ln(HCOO)3 (Ln = Pr (8) and Nd (9)) have been synthesized and characterized by single crystal X-ray diffraction analysis. Although the Ln3+ ions in 1-7 have different radius, the trivalent lanthanide ions in 1-7 show the same coordinated environment. The well-defined single crystal structures of 8 and 9 are first samples for formate-bridged Ln3+ metallic complexes. The luminescent properties of solid samples of 2-5 at room temperature and the magnetic property of 2 have been also reported and discussed in this paper.

摘要

已合成了七个同构的一维链状Ln3+配合物Ln(BTA)(HCOO)(H2O)3(Ln = Pr (1)、Gd (2)、Eu (3)、Tb (4)、Dy (5)、Er (6) 和Yb (7)),以及两个甲酸根配位和桥连的三维Ln3+配合物Ln(HCOO)3(Ln = Pr (8) 和Nd (9)),并通过单晶X射线衍射分析对其进行了表征。尽管1-7中的Ln3+离子半径不同,但1-7中的三价镧系离子显示出相同的配位环境。8和9明确的单晶结构是甲酸根桥连Ln3+金属配合物的首个实例。本文还报道并讨论了2-5固体样品在室温下的发光性质以及2的磁性。
