Source of material
The title compound was synthesized as previously reported [5] from reaction of ethyl 2-cyano-3-ethoxyacrylate and 5-methyl-1-(4-methylphenyl)-1H-1,2,3-triazole-4-carbohydrazide in boiling ethanol for 2 h. The solid obtained was collected by filtration, washed with ethanol, dried and recrystallized from dimethylformamide to give colourless crystals in 73% yield (Mp. 296–297 °C; lit. Mp. 296–297 °C [5]).
Experimental details
All H atoms were placed in calculated positions and refined using a riding model. For the methyl groups, C—H bonds were fixed at 0.96 Å and Uiso(H) set to 1.5Ueq(C) with free rotation around the C—C bond (HFIX 137 in SHELX [3]). For the rest of the hydrogens, Uiso(H) was set to 1.2Ueq(C, N) with aromatic C—H and N—H distances of 0.93 and 0.86 Å respectively.
Comment
Compounds containing the triazole moiety show various biological activities [6], [7], [8], [9]. Therefore, various efficient synthetic processes have been developed for the production of 1,2,3-triazoles [10], [11], [12]. Recently, the crystal structures for related compounds have been published [13], [14].
The asymmetric unit consists of one molecule of the title compound. The molecule consists of two tolyl rings [A (C1—C7) and D (C16–C22)] and two triazolyl rings [B (N1—N3, C8—C10) and C (N6–N8, C13–C15)]. The twist angles between pairs of rings are 50.6(1)°, 59.2(1)° and 61.0(1)° for A/B, B/C and C/D respectively. The torsion angle (C11—N4—N5—C12) for the formyl dihydrazide group is −124.5(2)°.
The molecules are aligned roughly parallel to [−101] in the crystal. Interactions of π-π type occur between identical tolyl groups (D) of neighbouring molecules with a centroid-to-centroid distance of 4.8 Å. Tolyl (A) and triazolyl (B) rings also interact with a centroid-to-centroid distance of 4.0 Å. Weak C—H⋯X interactions occur with O and N atoms acting as acceptors and C⋯O and C⋯N distances in the range 3.14 Å to 3.46 Å.
