Lewis Acidic Pentafluoroorthotellurato Germanes and the Structural Characterization of the Germylium Ion [GePh3]+

Year: 2026

Type: article

Abstract: The properties of the strong Lewis acid Ge(OTeF5)4 are investigated experimentally and quantum-chemically and compared to other germanes with electron-withdrawing ligands. It readily forms the octahedral germanate [NEt4]2[Ge(OTeF5)6] upon reaction with two equivalents of [NEt4][OTeF5]. Additionally, germanes with the formula RxGe(OTeF5)4–x with R = Me, Ph and x = 3, 2, 1 have been characterized. Ph3GeOTeF5 was utilized to generate the germylium ion [GePh3][Al(OTeF5)4] by –OTeF5 abstraction with one of the strongest Lewis acids available─Al(OTeF5)3.
