摘要：The molecule of the title compound, C24H16BrN 3OS3, contains three approximately planar fragments, viz. an oxadiazole ring plus two adjacent thiophene 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) ?, respectively. The phenothia-zine unit adopts a butterfly conformation, with a dihedral angle of 38.06 (15)  between the terminal benzene rings. The dihedral angle between the 2,5-bis-(thiophen-2- yl)oxadiazole unit and the attached benzene ring is 15.35 (11)  . In the crystal, molecules form stacks along the b-axis direction; neighboring molecules within the stack are related by inversion centers, with shortest inter-centroid separations of 3.741 (2) and 3.767 (2) ?. ?
