Abstract: The title cocrystal, C₁₈H₁₅OP·C₆H₆O₂, belongs to a series of molecular systems based on triphenylphosphine P-oxide. The O atom of the oxide group acts as an acceptor for hydrogen bonds from OH groups of two hydroquinone molecules which lie on inversion centres [OO = 2.7451 (17) and 2.681 (2) Å]. The crystal structure is stabilized by weak C-HO hydrogen bonds, forming a C₂¹(8) chain which runs parallel to the [100] direction.
