✦ Synopsis
In the title compound, C 23 H 16 Cl 2 N 2 O 2 , intramolecular C-HÁ Á ÁCl and C-HÁ Á ÁN hydrogen bonds from the quinoline fragment form five-and six-membered rings, respectively. The quinoline ring system makes dihedral angles of 30.42 (1) and 81.17 (1) with the phenyl rings of the diphenylacetamide fragment. In the crystal structure, molecules are linked into chains along the b axis by intermolecular C-HÁ Á ÁO hydrogen bonds.
