The molecular structure of the title compound, C9H14O4S3, exhibits intramolecular C—HS hydrogen bonds. In the crystal, pairs of O—HO hydrogen bonds lead to the formation of centrosymmetric dimers, which are in turn connected by weak C—HO interactions. The combination of these interactions generates edge-fused R22(8) and R22(20) rings running along [211].

In the title compound, C14H8BrNO5, the benzene rings form a dihedral angle of 62.90 (7)°. The central ester group is twisted away from the nitro-substituted and bromo-substituted rings by 71.67 (7) and 8.78 (15)°, respectively. The nitro group forms a dihedral angle of 7.77 (16)° with the benzene ring to which it is attached. In the crystal, molecules are linked by weak C—HO interactions, forming C(12) chains which run along [001]. Halogen–halogen interactions [BrBr = 3.523 (3) Å] within the chains stabilized by C—HO interactions are observed.
