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.

The mol-ecule of the title compound, C(24)H(16)BrN(3)OS(3), contains three approximately planar fragments, viz. an oxadiazole ring plus two adjacent thio-phene groups, and two phenothia-zine benzene rings, with largest deviations from the least-squares planes of 0.051 (3), 0.019 (4) and 0.014 (3) Å, respectively. The phenothia-zine unit adopts a butterfly conformation, with a dihedral angle of ...
