Source of material

The title compound was prepared from the reaction of 3-(5-methyl-1-phenyl-1H-1,2,3-triazol-4-yl)-1-phenyl-1H-pyrazole-4-carbaldehyde with 3-methyl-1-phenyl-1H-pyrazol-5(4H)-one in ethanol in the presence of few drops of piperidine as catalyst under reflux for 1.5 h. The solid obtained on cooling was recrystallized from dimethylformamide to give colorless crystals of the title compound (Mp 267-268 °C) [5].

Experimental details

All hydrogen atoms were placed in calculated positions and refined using a riding model. Methyl C—H bonds were fixed at 0.96 Å, with Uiso = 1.5 Ueq(C), and were allowed to spin about the C—C bond. Aromatic C—H distances were set to 0.93 Å and Uiso of the H atoms set to 1.2 Ueq(C).

Comment

Some triazolylpyrazoles [6, 7] are at the center of attention due to their useful applications as antibacterial, antiviral and antitumor reagents, as well as pesticides and herbicides [8], [9], [10]. The asymmetric unit comprises one molecule of C29H23N7O. The triazole-pyrazole ring system (apart from the methyl protons) is planar with rms deviation of 0.0385 Å. The three phenyl rings are twisted from the triazole-pyrazole system with interplanar angles of 11.08(11)°, 42.42(9)° and 83.62(12)°. In the crystal structure, the planar segments of the molecules form a π-stack along [100].
