Crystal structure of (Z)-2-[(E)-2-benzylidenehydrazin-1-ylidene]-1,2-diphenylethanone

Abstract

The title compound, C21H16N2O, has an almost planar (r.m.s. deviation = 0.0074 Å) 1,2-dibenzylidenehydrazine backbone with an approximately orthogonal almost planar (r.m.s. deviation = 0.0368 Å) phenylethanone substituent on one of the imine C atoms. The dihedral angle between the two mean planes is 76.99 (4)°. In the crystal, molecules are linked via C—H...O hydrogen bonds and C—H...π contacts, forming a three-dimensional structure with molecules stacked along the a-axis direction.
