6-(4-Bromo-phen-yl)-2-(4-fluoro-benz-yl)imidazo[2,1-b][1,3,4]thia-diazole.

In the title compound, C(17)H(11)BrFN(3)S, the imidazothia-diazole and bromo-phenyl rings are individually almost planar, with maximum deviations of 0.0215 (4) and 0.0044 (4) Å, respectively, and are inclined at an angle of 27.34 (3)° with respect to each other. The dihedral angle between the mean planes of the fluoro-benzyl and imidazothia-diazole rings is 79.54 (3)°. The crystal structure is stabilized by inter-molecular C-H⋯N inter-actions resulting in chains of mol-ecules along the b axis.
