Hydroxyl Radical-π Interaction in a Single Crystal.

ABSTRACT: 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 radical (^•OH). In this work, we have stabilized ^•OH in the crystal, which has been obtained from the filtrate after separating the precipitate of the chromenopyridine radical (DCP(2)^•) from the reaction mixture. DCP(2)^• abstracts a hydrogen atom from dissolved water in the ethanolic filtrate to grow the single crystal containing DCPH(2) and ^•OH in the asymmetric unit. The crystal packing and computational studies suggest that π-^•OH and ^•OH···N hydrogen-bonding intera
