| Abstract: | The reaction of the ambidentate ligand 2-(3,4-dichlorophenyl)imino-N-(2-thiazin-2-yl)thiazolidine (TdTz) with CuCl2·2H2O results in the formation of two new copper complexes, which has been characterized in the solid state by elemental analysis, UV-Vis-NIR diffuse reflectance, electron paramagnetic resonance (EPR) spectroscopy, magnetic measurements, infrared spectroscopy and X-ray powder diffraction. These studies have revealed that the two copper complexes are linkage isomers, which the metal atom is four-coordinated by two chloride ions and one ligand TdTz that act as a N,N bidentate ligand in one case and as a N,S bidentate ligand in the other one. |
