Abstract: The reaction of 1-aminoanthraquinone with 7,7',8,8'-tetracyanoquinodimethane yielded the title charge-transfer complex, C14H9NO2·C12H4N4. The molecules 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, molecules are stacked into columns along the a-axis direction. Pairs of N-HN and N-HO interactions connect the molecules perpendicular to the stacking direction. Additionally, an intramolecular N-HO hydrogen-bond interaction is observed for 1-aminoanthraquinone.
