Crystal structure of 2-bromo-1,4-dihy-droxy-9,10-anthra-quinone.

ABSTRACT: In an attempt to brominate 1,4-diprop-oxy-9,10-anthra-quinone, a mixture of products, including the title compound, C14H7BrO4, was obtained. The mol-ecule is essentially planar (r.m.s. deviation = 0.029 Å) and two intra-molecular O-H⋯O hydrogen bonds occur. In the crystal, the mol-ecules are linked by weak C-H⋯O hydrogen bonds, Br⋯O contacts [3.240 (5) Å], and π-π stacking inter-actions [shortest centroid-centroid separation = 3.562 (4) Å], generating a three-dimensional network.
