2-Hydroxy-1,4-naphthoquinone

The title compound (C₁₀H₆O₃) crystallizes with two molecules per asymmetric unit. In both molecules, the naphthoquinone ring system is approximately planar with the hydroxyl H atoms located in the plane. The crystal packing shows the molecules assembled in infinite linear chains by means of O-H...O hydrogen bonds between alternating independent molecules.
