The crystal structure of the title compound, 2-isobutyl-6-(2',4'-dichlorophenyl)- imidazo[2,1-b]-1,3,4-thiadiazole (C14H13Cl2N3S, Mr = 326.23), has been synthesized by the treatment of 2-amino-5-isobutyl-1,3,4-thiadiazole with α-chloroaceto-2,4-dichlorophenone and determined by single-crystal X-ray diffraction. The crystal belongs to monoclinic, space group P21/n with a = 12.483(7), b = 8.420(4), c = 14.998(8)A,β= 105.770(10)°, V = 1517.0(14) A3, Z = 4, Dc = 1.428 g/cm3, S = 0.902, μMoKα) = 0.558 mm－1, F (000) = 672, R = 0.0579 and Wr = 0.1186. The X-ray analytic results showed that all ring atoms in the imidazothiadiazole moiety are almost coplanar. The dihedral angel between the phenyl group and hetero-cycle is 16.8(0.2)°.
