5. Compounds 6 and 7 were found to be monomers in the solid state with tetrahedron and octahedron geometry around Sn center, respectively. Cytotoxicity in vitro of compounds 1–7 and initial ligands was evaluated on human colon cancer (HCT-116), human breast cancer (MCF-7) and adenocarcinomic human alveolar basal epithelial (A-549) cells. The IC50 values varied in 0.17–200 µM range for compounds 1–4
