Hexanitratoaluminate

Hexanitratoaluminate is an anion of aluminium and six nitrate groups with formula [Al(NO<sub>3</sub>)<sub>6</sub>]<sup>3−</sup> that can form salts called hexanitratoaluminates.

Related compounds

Hexaperchloratoaluminate [Al(ClO<sub>4</sub>)<sub>6</sub>]<sup>3−</sup> has perchlorate groups instead of nitrate, and is similarly sensitive to water. Pentanitratoaluminates have five nitrate groups. Tetranitratoaluminates have only four nitrate groups.

Examples

A known salt is potassium hexanitratoaluminate K<sub>3</sub>[Al(NO<sub>3</sub>)<sub>6</sub>].

Tetramethylammonium hexanitratoaluminate can be formed from tetramethylammonium chloride, aluminium chloride and dinitrogen tetroxide diluted with nitromethane.

Rubidium hexanitratoaluminate also exists.
