1,5-Diamino-2,6-dibromo-9,10-anthraquinone

In the title compound, C14H8Br2N2O2, the molecular structure features intramolecular N—H...O [2.639 (2) Å and 130°] and N—H...Br [3.053 (2) Å and 114°] hydrogen bonding. Due to inversion symmetry, the asymmetric part of the unit cell consits of one half-molecule. In the crystal, inversion dimers linked by pairs of N—H...O [2.955 (2) Å and 135°] hydrogen bonds occur. The structure also features C=O...π [3.228 (2) Å] and Br...Br [3.569 (1) Å] contacts
