In the title compound, C22H24N4O, the terminal and central benzene rings make dihedral angles of 52.7 (3) and 43.8 (2)°, respectively, with the triazole ring. The dihedral angle between the benzene rings is 8.9 (2)°. The crystal structure features C—H⋯π interactions. The atoms of the terminal propenyl group are disordered over two sets of sites, with a refined occupancy ratio of 0.714 (14):0.286 (14).

Cg1 and Cg3 are the centroids of the N2-N4/C18/C19 1H-1,2,3-triazole and C11-C16 benzene rings, respectively.  Compounds containing an azomethine group (-CH=N-), known as Schiff bases are formed by the condensation of a primary amine with a carbonyl compound. Schiff bases are some of the most widely used organic compounds. They are used as pigments and dyes, catalysts, intermediates in organic synthesis, and as polymer stabilisers (Dhar & Taploo, 1982). In azomethine derivatives, the C=N linkage is essential for biological activity, several azomethines were reported to possess remarkable antibacterial, antifungal, anticancer and diuretic activities (Supuran et al., 1996). Triazoles are also important class of heterocycles because of their varied biological activities (Singh et al., 2012). 1,2,3-triazoles, are fivemembered, doubly unsaturated heterocycles, the ring consisting of three sequentially linked nitrogen atoms and two carbon atoms (Ajello & Cusmanos, 1940). The 1,2,3-triazole moiety has several good properties: high chemical stability (hydrolytic, oxidant, and reducing conditions), aromatic character, good hydrogen-bond-accepting ability and this moiety is relatively resistant to metabolic degradation (Holla et al., 2005). Therefore, compound (I), was synthesized and its Xray studies is reported here.
In the crystal, the molecular packing of (I) is stabilized by C-H···π interactions (Table 1).

Bond distances, angles etc. have been calculated using the rounded fractional coordinates. All su's are estimated from the variances of the (full) variance-covariance matrix. The cell e.s.d.'s are taken into account in the estimation of distances, angles and torsion angles Refinement. Refinement on F 2 for ALL reflections except those flagged by the user for potential systematic errors. Weighted R-factors wR and all goodnesses of fit S are based on F 2 , conventional R-factors R are based on F, with F set to zero for negative F 2 . The observed criterion of F 2 > σ(F 2 ) is used only for calculating -R-factor-obs etc. and is not relevant to the choice of reflections for refinement. R-factors based on F 2 are statistically about twice as large as those based on F, and R-factors based on ALL data will be even larger.
