title: 2,4,6-Triamino-1,3,5-triazine-1,3-diium aqua-penta-fluoridoaluminate.
abstract: The title compound, (C(3)H(8)N(6))[AlF(5)(H(2)O)], 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 [AlF(5)(H(2)O)](2-) octa-hedra and diprotonated melaminium cations. Cohesion is ensured by a three-dimensional network of hydrogen bonds.
