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—HN 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)].

In the title compound, C19H25N5O2, the morpholine ring has a chair conformation. The plane of the central benzene ring makes dihedral angles of 88.75 (12) and 60.02 (7)°, respectively, with the mean plane formed by the four planar C atoms of the morpholine ring and with the plane of the triazole ring. In the crystal, molecules are linked via C—Hπ interactions, forming slabs lying parallel to (10-1). The C atoms of the bridging ethylene group, between the morpholine and benzene rings, and the terminal ethene group of the prop-1-ene substituent attached to the triazole ring, are disordered over two sets of sites, with an occupancy ratio of 0.634 (13):0.366 (13).

The title compound, C21H22N2O, crystallizes with two independent molecules in the asymmetric unit. In both molecules, the anthracene ring systems are almost planar, with maximum deviations of 0.071 (8) and 0.028 (7) Å, and make dihedral angles of 73.4 (2) and 73.3 (2)° with the least-squares planes formed by the four C atoms of the morpholine rings, which adopt a chair conformation. An intramolecular C—Hπ interaction occurs. In the crystal, the packing is stabilized by weak C—HO hydrogen bonds, which connect pairs of molecules into parallel to the c axis, and C—Hπ interactions.
