The molecular structure of the title compound, [Cu(C11H16N3O3S)2], shows the CuII atom with a distorted square-planar coordination geometry from the N2O2 donor set of the two chelating 2-{[bis(dimethylamino)methylidene]amino}benzenesulfonate ligands. The CuII atom lies 0.065 (1) Å above the N2O2 plane and the Cu-O [2 × 1.945 (2) Å] and Cu-N bond lengths [1.968 (3) and 1.962 (3) Å] lie in expected ranges. The two aromatic ring planes make a dihedral angle of 85.48 (1)°.
