5-(2,4-Dichlorophenyl)-3-(4-nitrophenyl)-1,2,4-oxadiazole

Abstract

In the title compound, C14H7Cl2N 3O3, the dichlorophenyl and nitrophenyl rings form dihedral angles of 5.4 (2) and 4.0 (2) , respectively, with the oxadiazole ring. The nitro group is twisted out of the attached benzene ring by a dihedral angle of 10.4 (3) . In the crystal, molecules are linked into a chain along the a axis by C - H?N hydrogen bonds. 2010.
