title: Crystal structure of (E)-1-(2,4-di-nitro-phen-yl)-2-[(E)-5-phenyl-1-(p-tol-yl)pent-2-en-4-yn-1-yl-idene]hydrazine.
abstract: In the title compound, C24H18N4O4, the plane of the phenyl ring is inclined to those of the toluene ring and the di-nitro-substituted benzene ring by 66.96 (19) and 47.06 (18)°, respectively, while the planes of the two benzene rings are inclined to one another by 36.26 (19)°. There is an intra-molecular N-H⋯O hydrogen bond between the NH group and the O atom of a nitro group, forming an S(6) ring motif. In the crystal, mol-ecules are linked by C-H⋯O hydrogen bonds and C-H⋯π inter-actions, forming a three-dimensional network. There are also weak π-π inter-actions present involving the phenyl ring and the di-nitro-substituted benzene ring [inter-centroid distance = 3.741 (2) Å].
