Lattice vibrations of 1,2,4-triazole
Journal of the Chemical Society, Faraday Transactions 2, 1977The far-infrared spectra of polycrystalline 1,2,4-triazole (C2N3H3) and 1-2-4-[2H3]triazole have been recorded between 250 and 20 cm–1. Raman spectra have also been measured. The assignments of the observed frequencies to translatory and rotatory lattice modes were made on the basis of isotopic shift factors.

ChemInform Abstract: MOLECULAR STRUCTURE OF 1,2,4‐TRIAZOLE
Chemischer Informationsdienst, 1977Abstract The molecular structure of 1,2,4-triazole has been determined by gas phase electron diffraction. The intemuclear distances and bond angles were obtained by applying a least-squares analysis to the experimental intensity. The bond distances ( r g ) and bond angles were N 1 -N 2 = 1.380 ± 0.010 A, N 2 C 3 = 1.329 ± 0.009 A, C 3 -N 4 = 1 ...

Preparation of 1,2,4-Triazole Derivatives of S-Triazines
Journal of Pharmaceutical Sciences, 1965Eleven symmetrical triazine derivatives containing 1,2,4-triazole and 3-amino-1,2,4-triazole substituents have been prepared. The derivatives with 1,2,4-triazole substituents were synthesized by reacting N,N '-diformylhydrazine with certain amine derivatives of cyanuric chloride.

Australian Journal of Chemistry, 1975
A series of N-unsubstituted 1,2,4-triazol-3-ylpyridines was prepared for antiarthritic testing. Weak and scattered antiinflammatory activity was observed, with no clear structure-activity relationships. Some of the compounds, notably the 5-pyridyl-1,2,4-triazole-3-carboxylic acids, showed infrared bands characteristic of strong hydrogen bonding.
