چکیده
The title mol-ecule, C(18)H(14)N(6)O(4)S, adopts a U-shape with the aromatic groups lying syn and oriented in the same direction as the thio-phene S atom. Twists away from planarity are evident with the maximum deviation being found for a terminal nitro group: C/C/N/O = 19.0 (3)°. The conformation about each of the C=N bonds is E. In the crystal, centrosymmetrically related mol-ecules are connected via N-H⋯O(nitro) hydrogen bonds, forming 14-membered {⋯HNC(3)NO}(2) synthons. These are linked into layers via C-H⋯O(nitro) inter-actions with the primary inter-actions between layers being of the type C-H⋯π, where the π-system is the thio-phene ring.
