title: 1,2,3,4-Tetra-hydro-phenazine 5,10-dioxide.
abstract: The complete mol-ecule of the title compound, C(12)H(12)N(2)O(2), lies on two crystallographic symmetry elements: a twofold axis and a mirror plane. In the mol-ecular structure, the quinoxaline ring and two methyl-ene substituents lie on the mirror plane while the other two methyl-ene groups are disordered about the plane. The crystal packing is stabilized by weak inter-molecular π-π stacking inter-actions with centroid-centroid distances of 3.6803 (7) Å.
