2021-10-25T12:29:51Z urn:hdl:10324/49357 Synthesis of tris(3-pyridyl)aluminate ligand and its unexpected stability against hydrolysis: revealing cooperativity effects in heterobimetallic pyridyl aluminates García Romero, Álvaro Martín Álvarez, José Miguel Colebatch, Annie Louise Plajer, Alex J. Miguel San José, Daniel Álvarez González, Celedonio Manuel García Rodríguez, Raúl Producción Científica We report the elusive metallic anion [EtAl(3-py)3]− (3-py = 3-pyridyl) (1), the first member of the anionic tris(3-pyridyl) family. Unexpectedly, the lithium complex 1Li shows substantial protic stability against water and alcohols, unlike related tris(2-pyridyl)aluminate analogues. This stability appears to be related to the inability of the [EtAl(3-py)3]− anion to chelate Li+, which precludes a decomposition pathway involving Li/Al cooperativity. 2021-10-25T12:29:51Z 2021-10-25T12:29:51Z 2021 info:eu-repo/semantics/article Dalton Transactions, 2021, vol. 50, n. 37. p. 13059-13065 1477-9234 https://uvadoc.uva.es/handle/10324/49357 10.1039/D1DT02351A eng https://pubs.rsc.org/en/content/articlelanding/2021/DT/D1DT02351A info:eu-repo/semantics/openAccess http://creativecommons.org/licenses/by-nc-nd/4.0/ © 2021 Royal Society of Chemistry Attribution-NonCommercial-NoDerivatives 4.0 Internacional Royal Society of Chemistry
