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.

In the title compound, C9H11N3S, there is an intramolecular O—HO hydrogen bond involving the OH group and the adjacent methoxy O atom. The molecule is essentially planar, with the maximum deviation from the mean plane of the non-H atoms being 0.1127 (14) Å for the methyl C atom. In the crystal, molecules are connected via centrosymmetric pairs of N—HS and O—HO hydrogen bonds into a two-dimensional network parallel to (10-3).
