Predominantly covalent Mg—C bonds are present in dicyclopentadienylmagnesium, as indicated by 25 Mg‐NMR spectroscopy. The large range of the 25 Mg chemical shifts (ca. 200 ppm) also facilitates clarification of other controversial bonding behavior. For the investigation of Schlenk equilibria [eq. (a)], the method has the advantage that all three species can be identified directly.
