(H3O)2NaAl3F12, isostructural with A2NaAl3F12 (A = K+, Rb+, Cs+) fluorides having HTB‐type sheets

Authors:	Laurent Jouffret Jerome Lhoste Annie Hemon‐Ribaud Marc Leblanc Vincent Maisonneuve

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.

Keywords:	crystal structure dihydronium sodium trialuminum(III) dodecafluoride hexagonal tungsten bronze HTB‐type sheets
