The title compound, (C3H10N2)2[AlF6]F·3H2O, was obtained using the solvothermal method with aluminium hydroxide, HF and propane-1,3-diamine as precursors in ethanol as solvent. The structure consists of isolated [AlF6]3− octahedra, diprotonated propane-1,3-diamine cations [(H2dap)2+], free fluoride ions and water molecules of solvation. The Al—F bond lengths in the octahedral [AlF6]3− anions range from 1.7690 (19) to 1.8130 (19) Å, with an average value of 1.794 Å. Each [AlF6]3− anion is surrounded by three water molecules and by six diprotonated amine cations. The `free' fluoride ion is hydrogen bonded to four H atoms belonging to four dications and has a distorted tetrahedral geometry. The three water molecules are connected by hydrogen bonds, forming trimers that connect the AlF6 octahedra and dications into a three-dimensional framework.

The title compound was prepared from a starting mixture of Al(OH)3 (0.75 g) in 40% HF (0.8 ml) and ethanol (5 ml). 1,3- diaminopropane (1 ml) was added and mild hydrothermal conditions (463 K) were applied in a Teflon lined autoclave (25 mL). The resulting product was washed with ethanol and dried in air giving colorless single crystals of the title compound.
All non-hydrogen atoms were refined with anisotropic displacement parameters. The H atoms of the water molecules were located using difference Fourier methods and their positional and isotropic displacement parameters refined. The H atoms of the organic dications were included in the
at calculated positions and refined with a common isotropic thermal parameter.Data collection: STADI4 (Stoe, 1998); cell

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > 2sigma(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R– factors based on ALL data will be even larger. |

Hybrid solids, containing both organic and inorganic entities, have diverse crystal structures which can influence their physicochemical properties. In type I solid hybrids, interactions between organic and inorganic networks are generally weak (e.g. hydrogen bonds or van der Waals' interactions), whilst in type II hybrids, covalent bonds are generally established between the metal of the inorganic moiety and the organic moiety. Type II hybrid materials usually exhibit better thermal stability than those of type I. Many chemical systems have been explored by conventional hydro- solvothermal synthesis or microwave heating. This work deals with a new aluminium fluoride salt of hybrid type I prepared under solvothermal conditions. Its structure contains isolated AlF6 distorted octahedra hydrogen bonded to propane-1,3-diamine dications and water molecules, together with fluoride ions which are also hydrogen bonded to the organic dications (Figures 2-4).
