Abstract Ammonium benzyldithiocarbamate, represented as NH4L, was prepared and used in the complexation reaction involving three organotin(iv) salts, represented as R2SnCl2 (R = CH3, C4H9, and C6H5). The structures of the synthesized complexes [(CH3)2SnL2] (1), [(C4H9)2SnL2] (2), and [(C6H5)2SnL2] (3) were established using various spectroscopic techniques (Fourier transform infrared spectroscopy, 1H NMR, 13C NMR, and 119Sn NMR) and elemental analysis. Thermal decomposition of the complexes using thermogravimetric analysis under nitrogen showed no definite pathway in the pattern of the complexes even though they are structurally related. X-ray diffraction studies of the final residue showed a common diffraction pattern for the complexes and confirmed SnS as the product of the thermal treatment. Cytotoxicity studies of these complexes against the human tumor cell lines (HeLa and MCF-7) compared favorably with the used standard 5-fluorouracil drug, with complexes 2 and 3 showing very good activity toward the used cell lines.

二有机锡 (iv) 苄基二硫代氨基甲酸酯复合物：合成、表征以及热和细胞毒性研究

摘要 苄基二硫代氨基甲酸铵，以 NH4L 表示，制备并用于涉及三种有机锡 (iv) 盐的络合反应，表示为 R2SnCl2（R = CH3、C4H9 和 C6H5）。合成的配合物 [(CH3)2SnL2] (1)、[(C4H9)2SnL2] (2) 和 [(C6H5)2SnL2] (3) 的结构是使用各种光谱技术（傅里叶变换红外光谱，1H NMR）建立的、13C NMR 和 119Sn NMR）和元素分析。在氮气下使用热重分析对配合物进行热分解表明，即使它们在结构上是相关的，在配合物的模式中也没有明确的途径。最终残留物的 X 射线衍射研究显示了复合物的常见衍射图，并确认 SnS 是热处理的产物。
