2-(4-Chloro­phen­yl)-5-{3,4-dibut­oxy-5-[5-(4-chloro­phen­yl)-1,3,4-oxadiazol-2-yl]thio­phen-2-yl}-1,3,4-oxadiazole

In the title compound, C(28)H(26)Cl(2)N(4)O(4)S, the dihedral angles between the two chloro­phenyl rings and the two oxadiazol rings are 10.51 (4)° and 13.55 (3)°, respectively. The thio­phene ring is oriented at dihedral angles of 5.59 (4)°, 8.33 (4)° and 4.41 (4)°, 11.05 (3)°, respectively, with respect to the two oxadiazol and the two chloro­phenyl rings. The intra­molecular C—H⋯O hydrogen bond results in the formation of a five-membered ring. In the crystal structure, π–π contacts between the oxadiazol rings, the chloro­phenyl rings and the chloro­phenyl and oxadiazol rings [centroid–centroid distances = 3.428 (3) Å, 3.750 (3) Å and 3.768 (3) Å, respectively] are present.
