  • Description: <jats:p>The weakly coordinating properties of the [Al(OTeF<jats:sub>5</jats:sub>)<jats:sub>4</jats:sub>]<jats:sup>–</jats:sup> anion were studied by the synthesis and characterization of its tetraalkylammonium salts [NAlk<jats:sub>4</jats:sub>][Al(OTeF<jats:sub>5</jats:sub>)<jats:sub>4</jats:sub>] [Alk<jats:sub>4</jats:sub> = –(CH<jats:sub>3</jats:sub>)<jats:sub>4</jats:sub>, –(C<jats:sub>2</jats:sub>H<jats:sub>5</jats:sub>)<jats:sub>4</jats:sub>, –(C<jats:sub>2</jats:sub>H<jats:sub>5</jats:sub>)<jats:sub>3</jats:sub>CH<jats:sub>3</jats:sub>, –(C<jats:sub>3</jats:sub>H<jats:sub>7</jats:sub>)<jats:sub>4</jats:sub>, –(C<jats:sub>4</jats:sub>H<jats:sub>9</jats:sub>)<jats:sub>4</jats:sub>]. The one‐pot synthesis includes formation of the Brønsted acid in 1,2–difluorobenzene, H[Al(OTeF<jats:sub>5</jats:sub>)<jats:sub>4</jats:sub>]<jats:sub>(solv.)</jats:sub>, and its reaction with [NAlk<jats:sub>4</jats:sub>]Cl [Alk<jats:sub>4</jats:sub> = –(CH<jats:sub>3</jats:sub>)<jats:sub>4</jats:sub>, –(C<jats:sub>2</jats:sub>H<jats:sub>5</jats:sub>)<jats:sub>4</jats:sub>, –(C<jats:sub>2</jats:sub>H<jats:sub>5</jats:sub>)<jats:sub>3</jats:sub>CH<jats:sub>3</jats:sub>, –(C<jats:sub>3</jats:sub>H<jats:sub>7</jats:sub>)<jats:sub>4</jats:sub>, –(C<jats:sub>4</jats:sub>H<jats:sub>9</jats:sub>)<jats:sub>4</jats:sub>] to the corresponding salts. Single crystals were obtained for [N(C<jats:sub>4</jats:sub>H<jats:sub>9</jats:sub>)<jats:sub>4</jats:sub>][Al(OTeF<jats:sub>5</jats:sub>)<jats:sub>4</jats:sub>] and characterized by X‐ray diffraction analysis.</jats:p>
