SnCl molecules bridged by the bidentate ligand. Complex 1 consists of two crystallographically independent and chemically different coordination complexes, mononuclear and binuclear in equal proportion. The structures of these complexes were investigated by single-crystal X-ray analysis, elemental analyses, NMR spectroscopy as well as electronic absorption and emission spectroscopy. The three complexes exhibit in vitro antitumor activity against human breast cancer cell line, MCF7.
