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 center dot center dot center dot O = 2.7451 (17) and 2.681 (2) A S]. The crystal structure is stabilized by weak C-H center dot center dot center dot O hydrogen bonds, forming a C-2(1)(8) chain which runs parallel to the [100] direction.
