The compound Bu4N[MoO(dioxolene)2CN], where dioxolene corresponds to 3,5-di-tert-butyl-o-quinone in one of the two oxidation states shown below, is formed by the reaction of (Bu4N)CN with [MoO(DBCat)2]2. 13C NMR spectra in CD2Cl2 indicate the presence of two isomers in solution which interconvert rapidly at room temperature relative to the NMR time scale. Only one of these isomers has been isolated, and its crystal structure at 100 K has been determined. The structural data and variable temperature 1H and 13C NMR spectra are presented and discussed.
