[Display omitted] ► Coordination compound for MARY spectroscopy created. ► Luminescent complex Zn(hfac)2(PPO)2 synthesized. ► Larger positive charge capture radius of the complex as compared to the free ligand implied. MARY spectroscopy is finding increasing use in the studies of transient organic radical ions and their reactions. Extending this technique to organometallic species will broaden the class of potential target compounds and can help answer important mechanistic questions in organometallic and spin chemistry. We probed this approach using a tailored Zn(hfac)2(PPO)2 complex. The synthesized complex has quantum yield and fluorescence lifetime (n-decane solution) φ ∼0.8 and τ ∼1.3ns, respectively. For this type of complex it is the first observation of MARY spectra different from those of free ligand, thus implying participation of the complex in the development of the observed signal.
