Abstract

In a spin: Directly differentiating multiple Mg sites in Mg-containing MOFs by (25)Mg solid-state NMR spectroscopy is very challenging at natural abundance. By performing (25)Mg two-dimensional triple-quantum magic-angle spinning solid-state NMR experiments at a magnetic field of 21.1 T at natural abundance, four non-equivalent Mg sites with very similar local environments in α-Mg(3)(HCOO)(6) were unambiguously resolved (see figure).
