The structure of the obtained complex （B） was characterized by Infrared Spectroscopy （IR）, analysis centesimal composition, and theoretical study. The complex （B） has an octahedral structure, where a tin in the center takes an octahedral geometry and is coordinated by four atoms of chlorine and two thiocarbonyl sulfur atom （C=S） of the ligand.展开更多
