چکیده
The title compound, C(19)H(19)N(7)O(5), exhibits substitutional disorder of the ortho-nitro and cyano groups, with site-occupancy factors of 0.686 (7):0.314 (7). The two aromatic rings are essentially coplanar, with a dihedral angle of 6.6 (5)°. In the diethyl-amino group, the two ethyl groups lie on the same side of the amino-benzene plane. An intra-molecular N-H⋯N hydrogen bond links the amino and diazenyl groups.
