摘要

研究人员用芳香族羧酸配体（水杨酸盐）合成了两种新的双核镧系配合物 [Ln2(Hsal)3(NO3)6]-(C2H5N)3-nH2O（Ln = Gd、Eu）。通过各种技术，包括元素分析、红外光谱、粉末 X 射线衍射和 X 射线单晶衍射，对这两种配合物进行了广泛的表征。研究了镧系配合物的热行为和光致发光特性。研究发现，这两种配合物在 180 °C 下加热 1 小时后仍具有良好的热稳定性。

Synthesis, crystal structures, characterization and luminescent thermal stability of Eu(III) and Gd(III) complex

Two new dinuclear lanthanide complexes [Ln₂(Hsal)₃(NO₃)₆]·(C₂H₅N)₃·nH₂O (Ln = Gd, Eu) were synthesized with an aromatic carboxylic acid ligand (salicylate). Both complexes were extensively characterized by various techniques, including elemental analysis, infrared spectroscopy, powder X-ray diffraction, and X-ray single-crystal diffraction. The thermal behavior and photoluminescence properties of lanthanide complexes were investigated. It was found that the two complexes had good thermal stability even after heating at 180 °C for 1 h. Furthermore, the two complexes exhibit a unique luminescent thermal stability.

期刊介绍： Polyhedron publishes original, fundamental, experimental and theoretical work of the highest quality in all the major areas of inorganic chemistry. This includes synthetic chemistry, coordination chemistry, organometallic chemistry, bioinorganic chemistry, and solid-state and materials chemistry. Papers should be significant pieces of work, and all new compounds must be appropriately characterized. The inclusion of single-crystal X-ray structural data is strongly encouraged, but papers reporting only the X-ray structure determination of a single compound will usually not be considered. Papers on solid-state or materials chemistry will be expected to have a significant molecular chemistry component (such as the synthesis and characterization of the molecular precursors and/or a systematic study of the use of different precursors or reaction conditions) or demonstrate a cutting-edge application (for example inorganic materials for energy applications). Papers dealing only with stability constants are not considered.
