Crystal structure and Hirshfeld surface analysis of 2,2′-(phenylazanediyl)bis(1-phenylethan-1-one)

Abstract

The whole molecule of the title compound, C22H19NO2, 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, molecules are linked by C—H...O contacts with R22(12) ring motifs, and C—H...π interactions, resulting in ribbons along the c-axis direction. van der Waals interactions between these ribbons consolidate the molecular 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%) interactions.
