The binuclear title compound, [Cu2(C12H10N6S2)Cl2], possesses twofold rotational symmetry. The CuII atom occupies a four-coordinate pseudo-tetrahedral environment bound to one S atom, one imine N atom and one pyridine N atom from the N1,N2-bis(pyridin-2-yl)hydrazine-1,2-dicarbothioamidate ligand, and one Cl- anion. The metal atoms are connected via the bis-tridentate ligand into a binuclear structure. The molecule is bow-shaped with the pyridine rings inclined to one another by 51.56 (14)°. In the crystal, N-HCl hydrogen bonds lead to the formation of ribbons propagating along . These ribbons are connected via C-HCl, C-HS and - interactions [centroid-centroid distance = 3.6146 (19) Å], leading to the formation of a three-dimensional structure.
