Four nonequivalent magnesium sites with very similar local Mg environments in a Mg-containing metal–organic framework, microporous α-Mg3(HCOO)6, have been resolved by 25Mg natural-abundance triple-quantum magic-angle spinning (3QMAS) NMR spectroscopy at an ultrahigh magnetic field of 21.1 T.
This cover article features results obtained using the 21.1 T solid-state NMR spectrometer at the National Ultrahigh-Field NMR Facility for Solids (Ottawa, ON). If you are interested in using this spectrometer in your research please contact the Facility manager. http://nmr900.ca/contacts_e.html
