Structural information on divalent cations such as Mg 2+  should have important implications for magmatic liquids because of their abundance in the Earth.s interior; nevertheless, little is confirmed about their coordination environments. We here apply a  25 Mg triple-quantum magic-angle spinning (3QMAS) NMR technique at an ultra-high magnetic field (21.8 T) and successfully show the occurrence of multiple Mg sites in MgSiO 3  glass. We find that these sites are distinguished by the degree of polyhedral distortion, not by the coordination number. The present study concludes that the highly distorted MgO 6  species occur in MgSiO 3  glass, in strong contrast with a recent radial distribution study.
