摘要：
In the crystal structure of the title compound, C20H18N4O22+. 2NO(3)(-), two pyridinium rings form dihedral angles of 48.0 (2) and 33.3 (4)degrees with the mean quinoxaline plane, and a dihedral angle of 52.6 (2)degrees with each other. The orientation of the pyridinium rings is such that their N atoms face each other. Both pyridinium N-H groups participate in N-H . . .O hydrogen bonds involving the O atoms of the nitrate anions. There exist significant pi-pi interactions responsible for the formation of the stacks along the b axis of the crystal.
