1,2,3,4-Tetrahydrophenazine 5,10-dioxide

The complete molecule of the title compound, C12H12N2O2, lies on two crystallographic symmetry elements: a twofold axis and a mirror plane. In the molecular structure, the quinoxaline ring and two methylene substituents lie on the mirror plane while the other two methylene groups are disordered about the plane. The crystal packing is stabilized by weak intermolecular π–π stacking interactions with centroid–centroid distances of 3.6803 (7) Å.
