Abstract

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.
