The title compound, C(27)H(27)N(7)O(6), a Schiff base, was synthesized by the reaction of triethyl-enetetra-mine with 3-nitro-benzealdehyde. There are two independent mol-ecules in the asymmetric unit. The central aromatic ring in one mol-ecule makes dihedral angles of 23.99 (7) and 20.06 (6)° with the two terminal rings; for the second mol-ecule, these angles are 26.14 (6) and 24.64 (6)°.
