Ethyl 5-((1E)-1-{(E)-2-[1-(4-eth­oxy­carbonyl-3-methyl-1,2-oxazol-5-yl)ethyl­idene]hydrazin-1-yl­idene}eth­yl)-3-methyl-1,2-oxazole-4-carboxyl­ate

The complete mol­ecule of the title compound, C(18)H(22)N(4)O(6), is generated by the application of a twofold axis of symmetry. Twists are evident in the mol­ecule, i.e. between each —C=N—N group and the adjacent oxazole ring [dihedral angle = 46.08 (12) °] and between the latter and attached ester group [excluding the terminal methyl group; dihedral angle = 24.4 (7) °]. In the crystal, C—H⋯O and π–π [3.5990 (11) Å] contacts connect mol­ecules into supra­molecular arrays in the ac plane. These stack along the b axis, being connected by weak π–π [3.3903 (11) Å] inter­actions.
