Effects of pH on the synthesis of di-thiourea cadmium chloride

Abstract

In the present work, the effect of pH on the synthesis of (bis)thiourea cadmium chloride was studied by the chemical bathing technique. The obtained compound [CdCl2{SC(NH2)2}2] was characterized by techniques such as: X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FTIR). FTIR describes and identifies the vibrations of the bonds that make up the (bis)thiourea cadmium chloride molecule at both an acid and a basic pH. Using the DRX characterization technique, a greater disorder is observed in the crystalline structure for the synthesis developed at a basic pH compared to the synthesis carried out at an acidic pH, and it was determined that an acidic medium favors the obtaining of the cadmium chloride complex (bis)thiourea, so the applications for this compound will depend on the pH used for its synthesis.
