A compound previously reported as HAlF4 has been shown to be [pyridinium][Al3F10]. The structure of this phase was solved and refined using a combination of synchrotron X-ray and neutron powder diffraction techniques in association with a number of other analytical techniques. The structure consists of [Al3F10]n- sheets containing both corner-sharing (common) and edge-sharing (unusual) AlF6 octahedra. The sheets are separated by pyridinium cations oriented perpendicular to the sheets. The final crystallographic data are as follows: monoclinic, space group C2/m, a = 8.2706(3), b = 6.1998(3), c = 10.525(1) Å, β = 103.38(1)°, V = 525.0(1) Å3, and Z = 2. This compound appears to be another example of a layered clay-like aluminum fluoride. |
