In this work, three new di-and tri-organotin(IV) complex Ph 3 SnL, Bu 3 SnL, and Me 2 SnL 2 were successfully synthesized by reacting sulfamethoxazole drug as a ligand with different alkyl metal. The synthesized complexes were fully characterized by fourier transform infrared, 1 proton nuclear magnetic resonance, 13 carbon nuclear magnetic resonance, 119 tin nuclear magnetic resonance and ultraviolet-visible spectroscopies. Field emission scanning electronic microscopy was also applied to study the surface morphology of synthesized complexes. Using above techniques it was confirmed the chemical structure and purity of synthesized materials. In this work, these materials have been used as photo-stabilizers of PVC to reduce the photo-degradation of its polymeric chains. Many approaches were exhibited to evaluate the efficiency of prepared organotin(IV) complexes as photo-stabilizers such as FTIR, UV, weight loss, gel content, viscosity average molecular weight, light microscope, atomic force microscope, field emission scanning electron microscopy, and energy dispersive X-Ray (EDX) mapping. These studies were in agreement and demonstrated that new complexes work as excellent photo-stabilizers of PVC. Thus they reduce the photo-degradation of PVC films containing these complexes compare to blank PVC after irradiation for 300 h by UV light at wavelength 313 nm. It has also demonstrated that Ph 3 SnL shows the best result as photo-stabilizer. This is because the complex has highly conjugation system by three phenyl groups compare to other complexes. The outcomes have been got in this study is significantly important to decrease the consumption of PVC around the world which is causing huge threaten to the environment especially the marine eco-system.

Organotin materials have several applications in industry and medicine since it uses to prepare medications. Moreover, it is used as photo-stabilizers for different plastic polymers such as polyvinyl chloride, polystyrene, and polyvinyl alcohol. Herein, it is going to focus on one application which is utilizing organotin complexes as photo-stabilizers of polyvinyl chloride. Since organotin(IV) can easily obtained by oxidizing organotin(II) that is more stable. Organotin(IV) can be designed in different forms depending on the number of organic and anion groups connected to the tin such as mono-organotin, di-, tri-and tetra-compounds. There are several applications of organotin materials in both industrial and medicine areas and in this paper, we are going to study some of a significant photo-stabilizers and their applications and we are going to highlight the using of organotin materials as photo-stabilizers of plastic polymers especially the PVC polymeric films

Herein successfully synthesized new organotin(IV) complexBu2SnOL by reacting sulfamethoxazole drug as a ligand with dibutyltin (IV) oxide. The synthesized complex was fully characterized by Fourier transform infrared, 1proton nuclear magnetic resonance, 13carbon nuclear magnetic resonance, 119tin nuclear magnetic resonance and ultraviolet-visible spectroscopies. Field emission scanning electronic microscopy was also applied to study the surface morphology of synthesized complex. The above techniques have demonstrated that the complex was prepared with high percentage of purity. This type of compound has various applications in medicine and industry. For example, using it as photo–stabilizer of different plastic polymers (polyvinyl chloride, polystyrene and polyvinyl alcohol).
