Qu-anti-tative analysis of weak non-covalent inter-actions in (Z)-3-(4-chloro-phen-yl)-2-phenyl-acrylo-nitrile:...

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 inter-molecular C-H⋯N and C-H⋯Cl hydrogen bonds, and C-H⋯π inter-actions. The mol-ecules pack in columns and adjacent columns are linked by weak C-H⋯Cl inter-actions. The PIXEL energy analysis suggests that the inter-molecular C-H⋯π inter-actions 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.
