The triazole ring of the title compound, C20H20N4O, is normal to the central benzene ring, making a dihedral angle of 90.0 (3)°, and forms a dihedral angle of 69.2 (3)° with the terminal phenyl ring. The dihedral angle between the phenyl and benzene rings is 88.2 (3)°. The atoms of the terminal propenyl group are disordered over two sets of sites, with a site-occupancy ratio of 0.663 (13):0.337 (13). In the crystal, C—H
N contacts lead to the formation of a layer structure extending parallel to (011). Two weak C—Hπ interactions are also observed.

The asymmetric unit of the title compound, C17H21N5O2, contains two crystallographically independent molecules, which are linked by a C—HN hydrogen bond. The morpholine rings of both molecules adopt distorted chair conformations. The dihedral angles between the triazole and benzene rings are 12.8 (3)° in the first independent molecule in which the –N=C– group between the morpholine and benzene rings is disordered [site-occupancy ratio = 0.576 (7):0.424 (7)] and 88.1 (2)° in the second independent molecule. In the crystal, molecules are linked by C—HN hydrogen bonds along the [100] direction. In addition, one weak C—Hπ interaction and two weak π–π stacking interactions [centroid–centroid distances = 3.840 (3) and 3.823 (2) Å] between the triazole rings of adjacent molecules are observed. The atoms of the terminal propenyl groups in both molecules are disordered over two sets of sites [site-occupancy ratios = 0.691 (10):0.309 (10) and 0.705 (15):0.295 (15)].
