Abstract:
In the title compound, [Cu(C(8)H(5)Cl(2)N(3)OS)(C(3)H(7)NO)]·C(3)H(7)NO, the Cu(II) 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-dichloro-salicylaldehyde thio-semi-carb-azonate ligand and one O atom from dimethyl-formamide. At the same time, the Cu atom is in contact with S and Cl atoms from another two complexes [Cu⋯S and Cu⋯Cl = 2.9791 (2) and 3.3800 (3) Å, respectively], thereby forming a [4 + 2] coordination geometry. The crystal structure exhibits N-H⋯O and N-H⋯N hydrogen bonds.
