Novel complexes of 2-(N-3',5'-di-tert-butyl-4'hydroxyphenyl)–iminomethylphenol (L) with Me2SnBr2 (1), Ph3SnBr (2) and Bu2SnCl2 (3) have been synthesized. Single crystals of compounds 3 and L were obtained, the structures of which were studied by X-ray diffraction. The antioxidant activity of compounds 1-3 was investigated using the CUPRAC and DPPH tests. It was found that the Sn(IV) complexes are more active than the initial ligand L and the standard Trolox. Cytotoxicity of 1-3 was investigated on the cell lines of human colon cancer HCT-116 and human breast adenocarcinoma MCF-7 in the MTT test.
