2-(5-Bromothiophen-2-yl)-5-[5-(10-ethylphenothiazin-3-yl)thiophen-2-yl]-1,3,4-oxadiazole
The molecule of the title compound, C(24)H(16)BrN(3)OS(3), contains three approximately planar fragments, viz. an oxadiazole ring plus two adjacent thiophene groups, and two phenothiazine benzene rings, with largest deviations from the least-squares planes of 0.051 (3), 0.019 (4) and 0.014 (3) Å,...

Sumario: | The molecule of the title compound, C(24)H(16)BrN(3)OS(3), contains three approximately planar fragments, viz. an oxadiazole ring plus two adjacent thiophene groups, and two phenothiazine benzene rings, with largest deviations from the least-squares planes of 0.051 (3), 0.019 (4) and 0.014 (3) Å, respectively. The phenothiazine 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 intercentroid separations of 3.741 (2) and 3.767 (2) Å. |
