Title: The DuPont powder challenge: The crystal structure of [C{sub 5}NH{sub 6}][Al{sub 3}F{sub 10}] -- A cautionary tale

Abstract

A compound previously reported as HAlF{sub 4} has been shown to be [pyridinium][Al{sub 3}F{sub 10}]. 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 [Al{sub 3}F{sub 10}]{sub n}{sup {minus}} sheets containing both corner-sharing (common) and edge-sharing (unusual) AlF{sub 6} 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) {angstrom}, {beta} = 103.38(1){degree}, V = 525.0(1) {angstrom}{sup 3}, and Z = 2. This compound appears to be another example of a layered clay-like aluminum fluoride.
