Modifying the donor properties of tris(pyridyl)aluminates in lanthanide(II) sandwich compounds García Rodríguez, Raúl Kopf, Sara Wright, Dominic Simon Química organometálica Química bioinorgánica Organometallic chemistry Bioinorganic chemistry 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. 2019-01-17 Ministerio de Economía, Industria y Competitividad - Agencia Estatal de Investigación (AEI) European Social Fund (ESF) Ramón y Cajal contract (RG-R, RYC-2015–19035) 2018-12-11T11:56:09Z 2019-01-17T00:40:19Z 2018 info:eu-repo/semantics/article https://doi.org/10.1039/C7DT04657J Dalton Transactions, 2018, Issue 7, Pages 2232-2239 1477-9226 http://uvadoc.uva.es/handle/10324/33406 eng https://pubs.rsc.org/en/Content/ArticleLanding/2018/DT/C7DT04657J Attribution-NonCommercial-NoDerivatives 4.0 International info:eu-repo/semantics/openAccess http://creativecommons.org/licenses/by-nc-nd/4.0/ application/pdf Royal Society of Chemistry
