In the title compound, C(14)H(15)N(3)S, the imidazo[2,1-b][1,3,4]thia-diazole fused-ring system is close to planar, with a maximum deviation of 0.042 (1) Å, and the dihedral angle between it and the phenyl ring is 24.21 (6)°. The isobutyl group is disordered over two sets of sites in a 0.899 (9):0.101 (9) ratio. In the crystal, weak aromatic π-π stacking… (More)
