Schiff base organotin(IV)complex C1 has been synthesized via the reaction of the o-vanillin-4-chloride-2-aminophenol Schiff base (H2 L)with the butyltin trichloride.The complex has been characterized by IR,1 H NMR,13 C NMR spectra,elemen-tal analysis and X-ray diffraction.The UV-vis spectra of the complex was determined.The anticancer activity of the Schiff base ligand (H2 L)and complex C1 against five species of cancer cell which are Hela,MCF7,HepG2,Colo205,NCI-H460 were tested respectively,and the tests showed that the complex was more active than carboplatin against tested MCF7,NCI-H460 can...
