García Rodríguez, Raúl Kopf, Sara Wright, Dominic Simon 2018-12-11T11:56:09Z 2019-01-17T00:40:19Z 2018 Dalton Transactions, 2018, Issue 7, Pages 2232-2239 1477-9226 http://uvadoc.uva.es/handle/10324/33406 10.1039/C7DT04657J 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. eng info:eu-repo/semantics/openAccess http://creativecommons.org/licenses/by-nc-nd/4.0/ Attribution-NonCommercial-NoDerivatives 4.0 International Modifying the donor properties of tris(pyridyl)aluminates in lanthanide(II) sandwich compounds info:eu-repo/semantics/article
