Abstract
The asymmetric unit of the title compound, C16H14Cl2N2O, comprises two similar molecules, A and B, in which the dihedral angles between the two aromatic rings are 70.1 (3) and 73.2 (2)degrees, respectively. The crystal structure features short C-H center dot center dot center dot Cl and C-H center dot center dot center dot O contacts and C-H center dot center dot center dot pi and van der Waals interactions. The title compound was refined as a two-component non-merohedral twin, BASF 0.1076 (5). The Hirshfeld surface analysis and two-dimensional fingerprint plots show that H center dot center dot center dot H (38.2% for molecule A; 36.0% for molecule B), Cl center dot center dot center dot H/H center dot center dot center dot Cl (24.6% for molecule A; 26.7% for molecule B) and C center dot center dot center dot H/H center dot center dot center dot C (20.0% for molecule A; 20.2% for molecule B) interactions are the most important contributors to the crystal packing.
