3-[5,6-Dimethyl-1,3-benzothiazol-2-yl)diazenyl]-1-methyl-2-phenyl-1H-indole

In the title compound, C24H20N4S, the phenyl ring forms a dihedral angle of 49.22 (7)° with the indole ring system. The indole and benzothiazole ring systems are both approximately planar, with dihedral angles between the five- and six-membered rings of 0.98 (7) and 1.28 (5)°, respectively. They are also oriented relative to the central N=N double bond at angles of 3.12 (14) and 3.82 (10)°, respectively.
