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.
