Methyl 3-[(1-benzyl-4-phenyl-1H-1,2,3-triazol-5-yl)formamido]­propano­ate: crystal structure, Hirshfeld surface analysis and computational chemistry

The title compound, C20H20N4O3, is constructed about a tri-substituted 1,2,3-triazole ring, with the substituent at one C atom flanked by the C and N atoms being a substituted amide group, and with the adjacent C and N atoms bearing phenyl and benzyl groups, respectively; the dihedral angle between the pendant phenyl rings is 81.17 (12)°, indicative of an almost orthogonal disposition. In the crystal, pairwise amide-N—H⋯O(carbon­yl) hydrogen bonds lead to a centrosymmetric dimer incorporating methyl­ene-C—H⋯π(benzene) inter­actions. The dimers are linked into a supra­molecular layer in the ab plane via methyl­ene-C—H⋯N(azo) and benzene-C—H⋯O(amide) inter­actions; the layers stack along the c-axis direction without directional inter­actions between them. The above-mentioned inter­molecular contacts are apparent in the analysis of the calculated Hirshfeld surface, which also provides evidence for short inter-layer H⋯C contacts with a significant dispersion energy contribution.
