Source of material

The title compound was synthesized based on a literature procedure [5] and recrystallized from dimethylformamide to give colourless block crystals (86%).

Experimental details

All hydrogen atoms were placed in calculated positions and refined using a riding model. N—H bonds were fixed at 0.86 Å (AFIX 43 instruction in SHELXL [4]), with displacement parameters 1.2 times Ueq(N). Aromatic C—H distances were set to 0.93 Å (AFIX 43) and their Uiso(H) set to 1.2 times the Ueq(C). Methyl C—H distances were set to 0.96 Å and their Uiso(H) to 1.5 times the Ueq(C) with the groups allowed to rotate about the C—C bonds (AFIX 137). O—H bonds were fixed at 0.82 Å (AFIX 147), with displacement parameters 1.2 times Ueq(O).

Comment

Various 1H-1,2,3-triazoles show miscellaneous biological activities [6], [7], [8], [9], [10]. Recently, we have reported the crystal structures for two 1H-1,2,3-triazole-4-carbohydrazides [11], [12] .

The asymmetric unit consists of two crystallographically independent molecules (cf. the figure). Bond lengths and angles excellently fit with those of our previous experiments [11], [12] . The twist angles between the planes through the hydroxyphenyl and the triazolyl groups are 3.37(6)° for molecule (C1—C18, A) and 6.02(6)° for the molecule (C19—C36, B). The angles between the planes through the triazolyl and phenyl groups are 37.05(6)° for A and 46.14(6)° for B.

The molecules are stacked along [010] in the crystal structure with A and B forming separate columns. Interactions of π—π type occur between hydroxyphenyl and triazolyl groups of neighbouring molecules related by inversion symmetry within the columns. The associated centroid-to-centroid distances are 3.97 Å and 3.66 Å for molecules A and B respectively. Intramolecular O—H⋯N hydrogen bonds are observed with O⋯N distances of 2.561(2) Å and 2.540(2) Å and O—H⋯ N angles of 144.3° and 143.8° for A and B respectively.
