The charge-transfer complex 1-amino-anthraquinone-7,7',8,8'-tetra-cyano-quinodimethane (1/1).


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.
