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.
我们合成了七种同构一维链 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)),以及两种
甲酸配位和桥接三维 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。虽然 1-7 中的 Ln3+ 离子具有不同的半径,但 1-7 中的三价
镧系离子显示出相同的配位环境。8 和 9 的单晶结构非常清晰,是第一个格式桥接 Ln3+
金属配合物的样品。本文还报告并讨论了 2-5 固体样品在室温下的发光特性以及 2 的磁性能。
