Crystal structure and Hirshfeld surface analysis of 2,2'-(phenyl-aza-nedi-yl)bis-(1-phenyl-ethan-1-one).

The whole mol-ecule of the title compound, C 22 H 19 NO 2 , is generated by twofold rotational symmetry. The N atom exhibits a trigonal-planar geometry and is located on the twofold rotation axis. In the crystal, mol-ecules are linked by C-H⋯O contacts with R 2 2 (12) ring motifs, and C-H⋯π inter-actions, resulting in ribbons along the c- axis direction. van der Waals inter-actions between these ribbons consolidate the mol-ecular packing. Hirshfeld surface analysis indicates that the greatest contributions to the crystal packing are from H⋯H (45.5%), C⋯H/H⋯C (38.2%) and O⋯H/H⋯O (16.0%) inter-actions.
