3-Bromo-7-meth­oxy-2-phenyl­imidazo[2,1-b][1,3]benzothia­zole

In the title mol­ecule, C₁₆H₁₁BrN₂OS, the central imidazo[2,1-b][1,3]benzothia­zole tricycle is essentially planar (r.m.s. deviation = 0.021 Å). The terminal phenyl ring is twisted at 36.18 (5)° from the mean plane of the tricycle. In the crystal, pairs of eak C—H...O hydrogen bonds link mol­ecules into centrosymmetric dimers, which are further packed into stacks along the a axis.
