Li₃SO₃N has been prepared by the mechanochemical reaction between lithium sulfamate (LiSO₃NH₂) and lithium amide or lithium hydride. This is the first example of an anhydrous compound containing the rare [SO₃N]^3- polyanion. Li₃SO₃N adopts the low-temperature Pmn21β structure of isoelectronic Li₃PO₄. Structural refinement from neutron powder diffraction data supports disordering of nitrogen over two of the three anion sites, although a fully disordered model cannot be conclusively refuted. While the compound is a poor ionic conductor, it is electrochemically stable to at least 5 V vs. Li⁺/Li⁰. This simple mechanochemical pathway should be suitable for preparing a host of other alkali-rich nitrogen-containing polyanionic compounds.
