García Rodríguez, Raúl Kopf, Sara Wright, Dominic Simon Producción Científica The coordination ability of tris(pyridyl)aluminates can be modified by the steric and electronic character of substituents at the 6-positions of their pyridyl rings. Whereas [EtAl(6-Me-2-py)3]− (1) coordinates strongly to lanthanide(II) ions [Eu(II) and Yb(II)], [EtAl(6-Br-2-py)3]− (2) forms much weaker complexes, and [EtAl(6-CF3-2-py)3]− does not coordinate at all. The modification of the donor ability of these ligands is investigated by solid-state studies of the Ln(II) sandwich compounds and by competitive coordination studies in solution. 2018-12-11 2019-01-17 2018 info:eu-repo/semantics/article Dalton Transactions, 2018, Issue 7, Pages 2232-2239 1477-9226 http://uvadoc.uva.es/handle/10324/33406 10.1039/C7DT04657J eng https://pubs.rsc.org/en/Content/ArticleLanding/2018/DT/C7DT04657J info:eu-repo/semantics/openAccess http://creativecommons.org/licenses/by-nc-nd/4.0/ Attribution-NonCommercial-NoDerivatives 4.0 International Royal Society of Chemistry
