A Schiff-Base Bibracchial Lariat Ether Forming a Cryptand-like Cavity for Lanth...
González-Lorenzo, Marina; Platas-Iglesias, Carlos; Avecilla, Fernando; Geraldes, Carlos F. G. C.; Imbert, Daniel; Bünzli, Jean-Claude G.We report here a structural and photophysical study of lanthanide(III) complexes with the di-deprotonated form of the bibracchial lariat ether N,N‘-bis(2-salicylaldiminobenzyl)-1,10-diaza-15-crown-5. The X-ray crystal structures of [Ce(L2-2H)](ClO4)·0.5H2O (2) and [Sm(L2-2H)](ClO4)·C3H8O (5b) show the metal ion being nine-coordinated and deeply buried in the cavity of the dianionic receptor. Thanks to the forma...
