Numerous attempts for organic radical stability mostly entail steric hindrance, spin-delocalization, supramolecular interaction with the host, π-π interactions, and hydrogen bonding. To date, there is no report of single crystals containing a hydroxyl (•OH). In this work, we have stabilized •OH in crystal, which has been obtained from filtrate after separating precipitate chromenopyridine (DCP(2)•) reaction mixture. DCP(2)• abstracts atom dissolved water ethanolic to grow crystal DCPH(2) asymmetric unit. The packing computational studies suggest that π-•OH •OH···N hydrogen-bonding interactions are responsible stabilizing •OH. presence further confirmed by mass analysis 2,2,6,6-tetramethylpiperidin-1-yl)oxyl (TEMPO) adduct.
