In the title compound, C10H10N4O2S2, the tetrazole and benzene rings are almost normal to one another, with a dihedral angle between their planes of 84.33 (9)°. In the crystal, molecules are linked via pairs of bifurcated O—H(N,N) hydrogen bonds, forming inversion dimers with graph-set motif R44(12). The dimers are linked by significant π–π interactions involving inversion-related tetrazole rings and inversion-related benzene rings, with centroid–centroid distances of 3.7376 (14) and 3.8444 (15) Å, respectively.

In the title compound, C15H11BrN4O2S, the tetrazole ring makes dihedral angles of 45.97 (10) and 75.41 (1)°, respectively, with the benzoyl and bromobenzene rings while the dihedral angle between the benzene rings is 73.77 (1)°. In the crystal, molecules are linked through O—H N and C—H O hydrogen bonds, giving infinite chains in both the [110] and [1-10] directions. These chains are further connected by C—Brπ and C—Oπ interactions and also by π–π stacking between tetrazole rings [centroid–centroid distance = 3.312 (1) Å], generating a three-dimensional network.
