Three-centre hydrogen bonds in triphenylphosphine oxide–hydroquinone (1/1)

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 [O...O = 2.7451 (17)...

Description
Summary: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 [O...O = 2.7451 (17) and 2.681 (2) Å]. The crystal structure is stabilized by weak C—H...O hydrogen bonds, forming a C21(8) chain which runs parallel to the [100] direction.
