Abstract: The title complex, [Cu₂(C₂₂H₁₆N₄O₄S₂)₂(NH₃)₄]·2H₂O, is a centrosymmetric dimer. The two copper ions are bridged by two 4,5-dicyano-N,N'-bis(p-tolylsulfonyl)-o-phenylenediamine ligands; the CuCu distance is 8.749 (1) Å. Each copper ion is in a distorted square-pyramidal geometry, defined by two N atoms from one ligand, two N atoms from two coordinated ammonia molecules and one CN from the other ligand apically. The hydrogen-bonding network leads to a layered structure.
