ABSTRACT
The reaction of 1-amino-anthraquinone with 7,7',8,8'-tetra-cyano-quinodimethane yielded the title charge-transfer complex, C(14)H(9)NO(2)·C(12)H(4)N(4). The mol-ecules have maximum deviations from the mean planes through the non-H atoms of 0.0769 (14) Å for an oxo O atom and 0.1175 (17) Å for a cyano N atom, respectively. The dihedral angle between the two planes is 3.55 (3)°. In the crystal, mol-ecules are stacked into columns along the a-axis direction. Pairs of N-H⋯N and N-H⋯O inter-actions connect the mol-ecules perpendicular to the stacking direction. Additionally, an intra-molecular N-H⋯O hydrogen-bond inter-action is observed for 1-amino-anthraquinone.
