In the title compound, C(17)H(19)N(5)O(5), obtained from the condensation reaction of 4-diethyl-amino-2-hy-droxy-benzalde-hyde and 2,4-dinitro-phenyl-hydrazine, the two benzene rings are twisted by a dihedral angle of 1.75 (12)°. The nitro groups are slightly twisted with the respect to the benzene ring to which they are attached, making dihedral angles of 8.20 (15) and 5.78 (15)°. An intra-molecular O-H⋯N hydrogen bond occurs. In the crystal, mol-ecules are linked by pairs of inter-molecular N- ...[more]
