Solid‐state25Mg magic angle spinning nuclear magnetic resonance (MAS NMR) data are reported from a range of organic and inorganic magnesium–oxyanion compounds at natural abundance. To constrain the determination of the NMR interaction parameters (δiso,χQ,ηQ) data have been collected at three external magnetic fields (11.7, 14.1 and 18.8 T). Corresponding NMR parameters have also been calculated by using density functional theory (DFT) methods using the GIPAW approach, with good correlations being established between experimental and calculated values of bothχQandδiso. These correlations demonstrate that the25Mg NMR parameters are very sensitive to the structure, with small changes in the local Mg2+environment and the overall hydration state profoundly affecting the observed spectra. The observations suggest that25Mg NMR spectroscopy is a potentially potent probe for addressing some key problems in inorganic materials and of metal centres in biologically relevant molecules.
