Abstract

[H₃tren]ṡ(AlF₆)ṡH₂O, [H₃tren]ṡ(AlF₆)ṡHF and [H₄tren]ṡ(MF₆)ṡ(F) ( M = Al, Fe), are obtained by hydrothermal technique and microwave heating in the (Al(OH)₃,FeF₃)-tren-(HF/H₂O)-ethanol system. Structure determinations are performed from single crystal X-ray diffraction data. All phases are built up from (MF₆)^3- anions linked by hydrogen bonds to [H₃tren]³⁺ or [H₄tren]⁴⁺ cations and to water or HF molecules or "isolated" fluoride anions. [H₃tren]³⁺ and [H₄tren]⁴⁺ cations adopt a "spider" shape configuration. Surprisingly, the HF molecule is strongly hydrogen bonded with one fluoride ion of the AlF₆ octahedron ( d_F⋯F = 2.38 Å ) in [H₃tren]ṡ(AlF₆)ṡHF while "isolated" fluoride ion is weakly coordinated by three hydrogen atoms in [H₄tren]ṡ(MF₆)ṡ(F). The evolution of the formulations, from [H₃tren]ṡ(AlF₆)ṡH₂O to [H₃tren]ṡ(AlF₆)ṡHF and to [H₄tren]ṡ(MF₆)ṡ(F) ( M = Al, Fe), is linked with the increase of the HF content of the starting solution. The volumes per formula unit decrease from 321.3(1) Å³ and 320.6(1) Å³ in [H₃tren]ṡ(AlF₆)ṡH₂O and [H₃tren]ṡ(AlF₆)ṡHF, respectively, to 298.5(4) Å³ in [H₄tren]ṡ(AlF₆)ṡ(F).
