In the title compound, [Cu₂(C₈H₁₁N₂O₃S)₂Cl₂], the Cu atoms are five-coordinated in a distorted square-pyramidal geometry by three donor atoms of the deprotonated anionic 2-(2-pyridylmethylamino)ethanesulfonate (pmt) ligand and two Cl atoms. The Cl atoms bridge two Cu atoms, giving a binuclear structure; the centroid of the Cu₂Cl₂ ring lies on a crystallographic center of inversion. The complex is stabilized by hydrogen bonds and [pi] - [pi] stacking interactions [average interplanar distance = 3.4969 (1) Å and ring-centroid separation distance = 4.1068 (4) Å].
