Sumario:The structure of the title compound, C(11)H(12)BrN(2)S(+)·C(2)HO(4) (−) (common name 6-bromo­levamisole hydrogen oxalate), is stabilized mainly by hydrogen bonds. Hydrogen oxalate anions form parallel coplanar chains via O—H⋯O hydrogen bonds, while there are N—H⋯O hydrogen-bonding inter­actions between the 6-bromo­levamisole cations and oxalate anions. Both five-membered rings from the 6-bromo­levamisole mol­ecule have a twist conformation. The mol­ecule has an extended conformation, with the 4-bromo­phenyl substituent positioned equatorially with N—C—C—C and C—C—C—C torsion angles of 39.8 (3) and 100.4 (3)°, respectively.
