Abstract The two 1-aryl-5-methyl-1, 2, 3-triazole derivatives were prepared by the 1-aryl-5- methyl-1, 2, 3-triazol-4-carboxylic acids 3. The yielded products 4a–b were confirmed by NMR, MS, IR spectra. We investigated the crystalline structure of compounds 4a and 4b. Compound 4a, C 9 H 8 BrN 3, Mr= 238.09, crystallizes in the monoclinic space group P2 (1)/n with unit cell parameters a= 11.660 (2), b= 7.668 (2), c= 11.818 (2) Å, α= 90.00, β= ...
