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

Abstract

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.
