(E)-1-(3-Nitro­phen­yl)-2-({5-[(1E)-2-(3-nitro­phen­yl)hydrazin-1-ylidenemeth­yl]-2-thien­yl}methyl­idene)hydrazine

The title mol­ecule, 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 thio­phene 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 mol­ecules 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) inter­actions with the primary inter­actions between layers being of the type C—H⋯π, where the π-system is the thio­phene ring.
