The most condensed crystalline fluoride that appears in the Al(OH)3-tren-HFaq.-ethanol system at 190 °C is found to be [H4tren]3/2·(Al6F24)·3H2O. The structure is monoclinic, P21/c, with a = 21.939(1) Å, b = 6.7180(2) Å, c = 23.329(1) Å, β = 111.324(2)°. (Al6F24) chains result from the connection of (Al7F30)9- polyanions by opposite AlF6 octahedra. Hydrogen bonds are established between the (Al6F24) chains and ordered or disordered [H4tren]4+ cations and water molecules.
