Magneto-Structural Characterization of Metallocene-Bridged Nitronyl Nitroxide Diradicals by X-Ray, Magnetic Measurements, Solid-state NMR Spectroscopy, and Ab Initio Calculations

Crystallization of ferrocene and ruthenocene substituted in the 1‐ and 1′‐positions by two nitronyl nitroxide radicals gave the new crystal phases β‐1 (besides the known phase α‐1), α‐2, and β‐2 whose structures were determined by X‐ray analysis. In β‐1 the radical moieties adopt transoid positions,...
