Tin thiocarbonohydrazone complexes: synthesis, crystal structures and biological evaluation
In this article, three organotin complexes formulated as [(Me) 2 Sn(H 2 L 1 )] ( 1 ), [(Ph) 2 Sn(H 2 L 1 )]·MeOH ( 2 ) and [(Me) 2 Sn(HL 2 )(OAc)] 4 (Me) 2 O ( 3 ) (H 4 L 1 = bis(2-hydroxybenzaldehyde) thiocarbohydrazone and H 2 L 2 = bis(2-acetylpyrazine) thiocarbonohydrazone) have been synthesized...

value on QSG7701 cells is 8.48 fold higher than that in HepG2 cells. In acute toxicity experiments, complex
