Abstract

In the title compound, C(28)H(28)N(4)O(4)S, the dihedral angles between the central thio-phene ring and its pendant oxadiazole rings are 1.2 (3) and 9.8 (3)°. The dihedral angles between the oxadiazole and phenyl rings are 2.9 (3) and 1.8 (3)°. Some short intra-molecular C-H⋯O contacts occur.
