2-(5-Bromo-thio-phen-2-yl)-5-[5-(10-ethyl-phenothia-zin-3-yl)thio-phen-2-yl]-1,3,4-oxadiazole.

ABSTRACT: 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 38.06?(15)° between the terminal benzene rings. The dihedral angle between the 2,5-bis-(thio-phen-2-yl)oxadiazole unit and the attached benzene ring is 15.35?(11)°. In the crystal, mol-ecules form stacks along the b-axis direction; neighboring mol-ecules within the stack are related by inversion centers, with shortest inter-centroid separations of 3.741?(2) and 3.767?(2)?Å.
