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

In the title compound, C(14)H(8)Br(2)N(2)O(2), 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 d...

Sumario:In the title compound, C(14)H(8)Br(2)N(2)O(2), 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.
