A. Cadiau, A. Hemon-Ribaud, M. Leblanc and V. Maisonneuve

Abstract: The title compound, (C₃H₈N₆)[AlF₅(H₂O)], was obtained by solvothermal synthesis from the reaction of aluminium hydroxide, 1,3,5-triazine-2,4,6-triamine (melamine), aqueous HF and water at 323 K for 48 h. The structure consists of [AlF₅(H₂O)]^2- octahedra and diprotonated melaminium cations. Cohesion is ensured by a three-dimensional network of hydrogen bonds.
