3-[5-Methyl-1-(4-methylphenyl)-1H-1,2,3-triazol-4-yl]-1-phenyl-1H-pyrazole-4-carbaldehyde

Abstract

The asymmetric unit of the title compound, C20H17N5O, consists of two independent molecules. The molecules comprise tolyl (A), triazolyl (B), pyrazolecarbaldehydyl (C) and phenyl (D) groups. The angles between the planes through neighouring rings A/B, B/C and C/D are 39.1 (1), 6.0 (1) and 12.6 (1)°, respectively, for the first molecule and 46.0 (1), 4.6 (1) and 8.5 (2)°, respectively, for the second. In the crystal, the two independent molecules form dimers linked by four C—H...O hydrogen bonds with each O atom accepting two such links.
