چکیده
In the title compound, C(36)H(44)N(4)O(4)S, the dihedral angles between the central thio-phene ring and the pendent oxadiazole rings are 12.7 (2) and 13.7 (2)°, and the dihedral angles between the oxadiazole rings and their adjacent benzene rings are 6.1 (2) and 17.5 (2)°. An intra-molecular C-H⋯O inter-action may help to establish the conformation.
