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).
