Tris(2-ammonioethyl)aminium decafluorominium monohydrate, (H4tren)[Al2F10]·H2O

Abstract

The title compound, (C6H22N4)[Al2F10]·H2O, was obtained by the reaction of aluminium oxide, tris(2-amino­ethyl)­amine (tren), HF and ethanol at 463 K for 1 h. It consists of (Al2F10)4− dimers, located on inversion centers, water mol­ecules and tetraprotonated tren cations. A network of hydrogen bonds ensures the three-dimensional cohesion.
