title: Ethyl 5-((1E)-1-{(E)-2-[1-(4-eth-oxy-carbonyl-3-methyl-1,2-oxazol-5-yl)ethyl-idene]hydrazin-1-yl-idene}eth-yl)-3-methyl-1,2-oxazole-4-carboxyl-ate.
abstract: The complete mol-ecule 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 mol-ecule, 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 mol-ecules into supra-molecular arrays in the ac plane. These stack along the b axis, being connected by weak π-π [3.3903 (11) Å] inter-actions.
