Quantitative analysis of weak non-covalent interactions in (Z)-3-(4-chlorophenyl)-2-phenylacrylonitrile: insights from PIXEL and Hirshfeld surface analysis

In the solid state, the title compound, C15H10ClN, is disordered over two orientations with a refined occupancy ratio of 0.86 (2):0.14 (2). The crystal structure is mainly stabilized by inter­molecular C—H⋯N and C—H⋯Cl hydrogen bonds, and C—H⋯π inter­actions. The mol­ecules pack in columns and adjacent columns are linked by weak C—H⋯Cl inter­actions. The PIXEL energy analysis suggests that the inter­molecular C—H⋯π inter­actions form a strong dimer in the major component. Hirshfeld analysis reveals that H⋯C, H⋯H, H⋯Cl and H⋯N contacts are the most important contributors to the crystal packing.
