The four dimethyl sulfoxide ligands of the title complex, [Cu(C2H6OS)4]2+.2ClO4-, adopt a tetrahedrally distorted square-planar arrangement around the central CuII ion, with all Cu-O bond lengths falling within the range 1.934 (6)-1.954 (6) Å. One O atom from each of the perchlorate anions interacts weakly at distances of 2.466 (8) and 2.640 (8) Å.
