4-Bromo-benzoic acid-6-(4-bromo-phen-yl)-3-methyl-1,2,4-triazolo[3,4-b][1, 3,4]thia-diazole (1/1)

Abstract

In the title 1:1 co-crystal, C10H7BrN 4S·C7H5BrO2, the triazolothia-diazole system is approximately planar [with a maximum deviation of 0.030 (4) Å] and forms a dihedral angle of 8.6 (1)° with the bromo-phenyl ring. In the carb-oxy-lic acid mol-ecule, the carboxyl group is rotated by 6.4 (3)° out of the benzene ring plane. The crystal structure features O-H⋯N and C-H⋯O hydrogen bonds, π-π stacking inter-actions [centroid-centroid distances = 3.713 (2), 3.670 (2) and 3.859 (3) Å] and short S⋯N [2.883 (4) Å] contacts.
