HexanitratoaluminateHexanitratoaluminate is an anion of aluminium and six nitrate groups with formula [Al(NO3)6]3− that can form salts called hexanitratoaluminates. Related compoundsHexaperchloratoaluminate [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] ExamplesA 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] References
