title: (H3O)2NaAl3F12, isostructural with A2NaAl3F12 (A = K(+), Rb(+), Cs(+)) fluorides having HTB-type sheets.
abstract: The title compound, (H3O)2NaAl3F12 [dihydronium sodium trialuminum(III) dodecafluoride], was obtained by solvothermal synthesis from the reaction of aluminium hydroxide, sodium hydroxide, 1,2,4-triazole and aqueous HF in ethanol at 463 K for 48 h. The structure consists of AlF6 octahedra organized in [AlF4(-)]n HTB-type sheets (HTB is hexagonal tungsten bronze) separated by H3O(+) and Na(+) cations.
