N-[5-(Diphenylamino)penta-2,4-diyn-1-yl]benzamide

Abstract

In the title compound, C24H18N2O1, the ynamine moiety has a near-planar structure (r.m.s. deviation = 0.0200 Å), and makes dihedral angles of 52.99 (7) and 27.91 (7)° with the phenyl rings. In the crystal, the molecules exhibit a dimeric form owing to bifurcated C—H...π interactions within a centrosymmetric dimer. Intermolecular N—H...O hydrogen bonds are also formed along the b-axis direction.
