The crystal structure of 6-(4-chloro­phen­yl)-2-(4-methyl­benz­yl)imidazo[2,1-b][1,3,4]thia­diazole-5-carbaldehyde

In the title imidazo[2,1-b][1,3,4]thia­diazole derivative, C(19)H(14)ClN(3)OS, the 4-methyl­benzyl and chloro­phenyl rings are inclined to the planar imidazo[2,1-b][1,3,4]thia­diazole moiety (r.m.s. deviation = 0.012 Å) by 64.5 (1) and 3.7 (1)°, respectively. The mol­ecular structure is primarily stabilized by a strong intra­molecular C—H⋯O hydrogen bond, leading to the formation of a pseudo-seven-membered S(7) ring motif, and a short intra­molecular C—H⋯N contact forming an S(5) ring motif. In the crystal, mol­ecules are linked by pairs of C—H⋯S hydrogen bonds, forming inversion dimers. The dimers are linked by C—H⋯O and C—H⋯π inter­actions, forming chains propagating along [110].
