In the title compound, [Cu(C8H5Cl2N3OS)(C3H7NO)]·C3H7NO, the CuII atom is coordinated in a slightly distorted square-planar geometry by an O, an S and an N atom from the tridentate ligand 3,5-dichlorosalicylaldehyde thiosemicarbazonate ligand and one O atom from dimethylformamide. At the same time, the Cu atom is in contact with S and Cl atoms from another two complexes [CuS and CuCl = 2.9791 (2) and 3.3800 (3) Å, respectively], thereby forming a [4 + 2] coordination geometry. The crystal structure exhibits N-HO and N-HN hydrogen bonds.
