Two independent molecules comprise the 24H26N4O. The major difference between them is found in the relative orientation of the triazole-bound p-tolyl group which have the opposite sense of twist [N—N—C—C torsion angles = 55.8 (3) and −49.8 (3)°]. The chalcone residue is almost coplanar with the triazole ring [N—C—C—O and C—C—C—C torsion angles = −178.9 (2) and −178.5 (2)°, respectively; cf. 177.9 (3) and 168.5 (3)°, respectively, in the second molecule]. The conformation about each C=C double bond is E and in each case the triazole methyl group is syn to the carbonyl O atom. In the crystal, molecules aggregate into layers parallel to (-113). The first independent molecule self-associates into a layer via C—H⋯O and C—H⋯π interactions. By contrast, layers comprising the second independent molecule do not feature specific interactions between molecules. The global crystal packing comprises alternating layers.

The title compound was prepared following a reported method (Abdel-Wahab et al., 2012). Yellow prisms were obtained from its DMF solution by slow evaporation at room temperature.
Carbon-bound H-atoms were placed in calculated positions (C—H = 0.93 to 0.97 Å) and were included in the
in the riding model approximation, with Uiso(H) = 1.2–1.5Uequiv(C).Triazole-based chalcone derivatives exhibit a range of biological activities (Abdel-Wahab et al., 2012; Guantai et al., 2010) and in this connection, the title compound was synthesized and characterized crystallographically.
In (I), Fig. 1, two independent molecules comprise the ═C13 and C36═C37 double bonds [1.329 (4) and 1.330 (4) Å] is E, and in each case the triazole-methyl is syn to the carbonyl-O atom. In these respects, the structure of (I) resembles closely that of a recently described derivative (Abdel-Wahab et al., 2013). The major difference between the two molecules in (I) is found in the relative orientation of the triazole-bound p-tolyl groups. Although having similar dihedral angles, see above, the orientations of the rings have the opposite sense as seen in the value of the N2—N1—C1—C2 torsion angle of 55.8 (3)° cf. -49.8 (3)° for N6—N5—C25—C26. Each of the piperidinyl rings has a chair conformation.
As illustrated in the overlay diagram, Fig. 2, variations exist in the relative orientations of the terminal substituents. In the central region of the molecule, the triazole-bound p-tolyl residue is twisted with respect to the five-membered ring, forming a dihedral angle of 56.88 (14)° [the comparable angle for the second independent molecule is 51.92 (16)°]. By contrast, the chalcone residue is co-planar as seen in the values of the N3—C11—C12—O1 and C11—C12—C13—C14 torsion angles of -178.9 (2) and -178.5 (2)°, respectively [cf. 177.9 (3) and 168.5 (3)°]. The conformation about each of C12In the π interactions, Fig. 3 and Table 1. The O2-containing molecules also assemble into a layer but without specific interactions between them. The global crystal packing comprises alternating layers of O1- and O2-containing layers with no specific interactions between them, Fig. 4.
centrosymmetrically related O1-containing molecules associate into dimers via C—H···O interactions and these are connected into a supramolecular layer, parallel to (-1 1 3), via C—H···For the biological activities of triazole-based chalcone derivatives, see: Abdel-Wahab et al.

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |

Triazole-based chalcone derivatives exhibit a range of biological activities (Abdel-Wahab et al., 2012; Guantai et al., 2010) and in this connection, the title compound was synthesized and characterized crystallographically.
In (I), Fig. 1, two independent molecules comprise the asymmetric unit. As illustrated in the overlay diagram, Fig. 2, variations exist in the relative orientations of the terminal substituents. In the central region of the molecule, the triazole-bound p-tolyl residue is twisted with respect to the five-membered ring, forming a dihedral angle of 56.88 (14)° [the comparable angle for the second independent molecule is 51.92 (16)°]. By contrast, the chalcone residue is co-planar as seen in the values of the N3—C11—C12—O1 and C11—C12—C13—C14 torsion angles of -178.9 (2) and -178.5 (2)°, respectively [cf. 177.9 (3) and 168.5 (3)°]. The conformation about each of C12═C13 and C36═C37 double bonds [1.329 (4) and 1.330 (4) Å] is E, and in each case the triazole-methyl is syn to the carbonyl-O atom. In these respects, the structure of (I) resembles closely that of a recently described derivative (Abdel-Wahab et al., 2013). The major difference between the two molecules in (I) is found in the relative orientation of the triazole-bound p-tolyl groups. Although having similar dihedral angles, see above, the orientations of the rings have the opposite sense as seen in the value of the N2—N1—C1—C2 torsion angle of 55.8 (3)° cf. -49.8 (3)° for N6—N5—C25—C26. Each of the piperidinyl rings has a chair conformation.
In the crystal structure, centrosymmetrically related O1-containing molecules associate into dimers via C—H···O interactions and these are connected into a supramolecular layer, parallel to (-1 1 3), via C—H···π interactions, Fig. 3 and Table 1. The O2-containing molecules also assemble into a layer but without specific interactions between them. The global crystal packing comprises alternating layers of O1- and O2-containing layers with no specific interactions between them, Fig. 4.
