2-(2,4-Dichloro­phen­oxy­meth­yl)-5-(4-methyl­phen­yl)imidazo[2,1-b][1,3,4]thia­diazole

In the title compound, C(18)H(13)Cl(2)N(3)OS, the eight atoms comprising the central imidazo/thia­diazo­lethia­diazole residue are coplanar (r.m.s. deviation = 0.009 Å). The dihedral angle of 8.72 (13)° between the dichloro­benzene and tolyl rings reflects a twist about the O—C(benzene) bond; the C(m)—O—C(b)—C(b) torsion angle = −168.5 (2)° (m = methyl­ene C and b is benzene C). Supra­molecular tapes along the b axis are found in the crystal structure which are mediated by π–π inter­actions occurring between centrosymmetrically related thia­diazole rings [inter-ring centroid distance = 3.6907 (16) Å] and between the benzene and tolyl rings [inter-ring centroid distance = 3.7597 (16) Å].
