2-Isobutyl-6-(4-meth-oxy-phen-yl)imidazo[2,1-b][1,3,4]thia-diazole.

In the title compound, C(15)H(17)N(3)OS, the dihedral angle between the statistically planar imidazo[2,1-b][1,3,4]thia-dia-zole fused-ring system (r.m.s. deviation = 0.002†à ) and the methyoxbenzene ring is 4.52†(6)°. In the crystal, mol-ecules are arranged into columns and stacked down the a axis. The crystal structure is stabilized by weak C-H⋯π and π-π inter-actions [centroid-centroid separations = 3.6053†(8) and 3.7088†(7)†à ].
