In the title compound, [Cu2(C11H13N3O3S)2(C2H6OS)2], the CuII cation is N,N',O-chelated by a deprotonated hy­droxy­imino-tosyl­hydrazone ligand and coordinated by a dimethyl sulfoxide mol­ecule. One O atom from the adjacent hy­droxy­imino-tosyl­hydrazone ligand bridges the CuII cation, forming the centrosymmetric dimeric complex. The cation is in an overall distorted N2O3 square-pyramidal coordination environment. The methyl­benzene ring is twisted with respect to the hydrazine fragment, with a dihedral angle of 89.54 (9)° between the planes. An intra­molecular C-H...O hydrogen bond occurs. In the crystal, mol­ecules are linked by weak C-H...O and C-H...S inter­actions. Weak [pi]-[pi] stacking is also observed between parallel benzene rings of adjacent mol­ecules, the centroid-centroid distance being 3.9592 (17) Å.
