Syntheses, Crystal Structures and Biological Activity of the 1D Chain Benzyltin Complexes Based on 2-Oxo-Propionic Acid Benzoyl Hydrazone

Two new 1D Chain benzyltin complexes {[C6H4(O)C=N–N=C(Me)COO](CH3OH)(C6H5CH2)2Sn}n (1), {[C6H4(O)C–NH–N=C(Me)COO](C6H5CH2)3Sn}n (2) were synthesized by the reactions of 2-oxo-propionic acid benzoyl hydrazone with dibenzyltin dichloride or tribenzyltin chloride, respectively. The two complexes were characterized by FT-IR, 1H, 13C and 119Sn NMR spectra, elemental analysis, X-ray single crystal diffraction and TGA. In vitro antitumor activities of...
