Hexanitratoaluminate

Hexaperchloratoaluminate [Al(ClO₄)₆]^3−[1] has perchlorate groups instead of nitrate, and is similarly sensitive to water. Pentanitratoaluminates have five nitrate groups.^[2] Tetranitratoaluminates have only four nitrate groups.^[3]

A known salt is potassium hexanitratoaluminate K₃[Al(NO₃)₆].

Tetramethylammonium hexanitratoaluminate can be formed from tetramethylammonium chloride, aluminium chloride and dinitrogen tetroxide diluted with nitromethane.^[4]

Rubidium hexanitratoaluminate also exists.^[5]
