2-[6-(4-Chloro-phen-yl)imidazo[2,1-b][1,3]thia-zol-2-yl]-N'-[(E)-4-meth-oxy-benzyl-idene]acetohydrazide

Abstract

In the imidazo[2,1-b][1,3]thia-zole group of the title compound, C(21)H(17)ClN(4)O(2)S, the dihedral angle between the thia-zole and imidazole rings is 1.9 (2)°. The mean plane of this group makes dihedral angles of 5.5 (2) and 39.9 (2)° with the benzene rings of the chloro-phenyl and meth-oxy-phenyl groups, respectively. The dihedral angle between these two benzene rings is 34.4 (2)°. In the crystal, mol-ecules are connected to each other by inter-molecular N-H⋯O hydrogen bonds along the b axis, generating a C(4) chain. Weak C-H⋯π inter-actions also occur.
