Name: 1H-1,2,4-Triazol-5-amine. Recently I am researching about HIRSHFELD SURFACE-ANALYSIS; X-RAY; BENZIMIDAZOLE; DERIVATIVES; OXIDATION; ISOMERISM; LIGAND; CO(II); ALPHA; ACID, Saw an article supported by the Fonds de la Recherche Scientifique-FNRSFonds de la Recherche Scientifique – FNRS [CDR 33694457]; bilateral WBI action with Morocco (COP 22 Program 2018-2022). Published in ELSEVIER SCIENCE INC in NEW YORK ,Authors: Chkirate, K; Fettach, S; El Hafi, M; Karrouchi, K; Elotmani, B; Mague, JT; Radi, S; Faouzi, ME; Adarsh, NN; Essassi, E; Garcia, Y. The CAS is 61-82-5. Through research, I have a further understanding and discovery of 1H-1,2,4-Triazol-5-amine
Two Cu(II) coordination complexes, C1 and C2 of the formula [Cu(4)2(H2O)(2)], have been prepared by reaction between CuCl2 center dot 2H(2)O and 7-ethoxycarbonylmethyl-5-methyl-1,2,4[1,5-a]pyrimidine (L) in a 1:2 M:L molar ratio. The L molecule decomposes during the reaction process into 7-carboxy-5-methyl-[1,2,4]-triazolo[1,5-a]pyrimidine (4) through an intermediate, ethyl 2,2-dihydroxy-2-(5-methyl-[1,2,4]triazolo[1,5-a]pyrimidin-7-yl) acetate (5), which has been isolated and its crystal structure determined by X-ray diffraction. The X-ray analysis of the single crystals of [Cu(4)(2)(H2O)(2)] obtained from the slow evaporation of EtOH and MeOH, separately, revealed the formation of solvent induced polymorphs C1 and C2, respectively. The primary supramolecular synthon for C1 and C2 are six membered ring, and square shaped hydrogen bonded architecture, respectively. The self-assembly of such synthons resulted in a two dimensional hydrogen bonded sheet supported by O-H center dot center dot center dot O interactions. In addition, the antioxidant properties of the ligands and its complexes were evaluated in vitro using 1,1-diphenyl-2-picrylhydrazyl acid, 2,2′-azino-bis (3-ethylbenzothiazoline-6 sulfonic acid radical scavenging methods and ferric reducing antioxidant power.
Bye, fridends, I hope you can learn more about C2H4N4, If you have any questions, you can browse other blog as well. See you lster.. Name: 1H-1,2,4-Triazol-5-amine
