Abstract: The title compound, [CuCl₂(C₁₀H₇ClN₂S)], crystallizes as neutral CuCl₂L [L = 2-chloro-6-(mercaptopyridin-2-yl)pyridine] molecular units. The copper(II) centre adopts a distorted four-coordinate geometry comprising the two pyridinyl N atoms of the bidentate chelating ligand [Cu-N 2.012  (2) and 2.029  (2)  Å] and the two chloride anions [Cu-Cl 2.2049  (6) and 2.2335  (6)  Å]. The dihedral angle quantifying the extent of the distortion of the geometry from square planar ( = 0°) towards tetrahedral ( = 90°) is 36.81  (6)°. There is evidence for the formation of dimeric units via ClS interactions.
