Abstract
The reactions of sodium 2-(quinolyl-8-iminomethyl)phenolate with rare-earth element chlorides afford homoleptic mononuclear complexes [Ln{2-(8-quinolyl)N=CH–C6H4O}3] (Ln = La (I), Nd (II), Eu (III), and Tb (IV)) with the nonacoordinated rare-earth element ion. All synthesized complexes are similar in structure, and complexes II, III, and IV are isostructural (CIF files CCDC nos. 2124365 (I), 2124364 (II), 2124366 (III), and 2124367 (IV)). Compounds III and IV exhibit no luminescence, and characteristic luminescence in the near-IR range is observed for complex II.
