✦ Synopsis

The principal molecule of the title molecule, C 12 H 8 -ClN 3 O 3 ÁC 3 H 7 NO, is essentially planar. The two benzene rings make a dihedral angle of only 6.9 (1) . The nitro group is slightly twisted with respect to the benzene ring to which it is attached [3.7 ( 1) ]. The dimethylformamide solvent molecule and the azobenzene molecule are linked through a strong O-HÁ Á ÁO hydrogen bond. In the crystal structure, the molecules are stacked throughinteractions along [010]. Some weak C-HÁ Á ÁO interactions stabilize the packing.
