In the two complexes, each six-coordinated Bi(III) atom adopts a pentagonal pyramidal configuration with six sulfur atoms from three ligands, and the dimmer structures are formed by weak interactions of Bi···S between two molecules. The anticancer activities of the two complexes were studied by evaluating their cytotoxicities against several human cancer cell lines using the MTT assay. Results indicated complex 2 showed moderate cytotoxic effects on the selected cancer cells.展开更多
