title: 1-[2-(3,4-Dichloro-phen-yl)-5-(3,4,5-trimethoxy-phen-yl)-2,3-dihydro-1,3,4-oxadiazol-3-yl]ethanone.
abstract: The title compound, C(19)H(18)Cl(2)N(2)O(5), was synthesized by the reaction of N'-(3,4-dichloro-benzyl-idene)-3,4,5-trimethoxy-benzo-hydrazide and acetic anhydride. The oxadiazole ring makes dihedral angles of 82.82 (7) and 9.92 (7)° with the 3,4-dichloro-benzene and the 3,4,5-trimethoxy-benzene ring planes, respectively. The crystal structure is stabilized by inter-molecular C-H⋯ O and C-H⋯ N hydrogen bonds. Intra-molecular C-H⋯O and C-H⋯N hydrogen bonds are also present.
