Synthesis and crystal structure of a luminescent compound 5-(1H-benzimidazol-2-yl)-3H-[1,2,3]triazole-4-carboxylic acid was written by Sun, Chen-Guang;Zeng, Ming-Hua;Xu, Kang-Zhen;Song, Ji-Rong. And the article was included in Chinese Journal of Structural Chemistry in 2012.Safety of 1H-1,2,3-Triazole-4,5-dicarboxylic acid This article mentions the following:
5-(1H-benzimidazol-2-yl)-3H-[1,2,3]triazole-4-carboxylic acid DMF solvate (C10H7N5O2.C3H7NO, Mr 302.30) was synthesized and characterized by FT-IR and ESI-MS, 1H-NMR spectroscopy and x-ray single-crystal diffraction [orthorhombic, space group Pna21, a 6.9635(3), b 19.4398(7), c 30.6165(12) Å, V 4144.5(3) Å3, Z 12, Dc 1.454 g/cm3, μ(MoKα) 0.108 mm-1, F(000) 1896, R 0.0450 and wR 0.0975 for 3578 observed reflections with I > 2σ(I)]. Crystals were grown from DMF by slow diffusion at room temperature Intermol. H bonds and π-π stacking further stabilize the structure. In the experiment, the researchers used many compounds, for example, 1H-1,2,3-Triazole-4,5-dicarboxylic acid (cas: 4546-95-6Safety of 1H-1,2,3-Triazole-4,5-dicarboxylic acid).
1H-1,2,3-Triazole-4,5-dicarboxylic acid (cas: 4546-95-6) belongs to triazole derivatives. Triazoles exhibit substantial isomerism, depending on the positioning of the nitrogen atoms within the ring.Triazole heterocyclic structures are found to form many weak nonbond interactions with the receptors and enzymes in biological systems.Safety of 1H-1,2,3-Triazole-4,5-dicarboxylic acid
