Abstract:

Tris(o-methylbenzyl)tin thiosalicylate(1) and di(m-fluorobenzyl)tin thiosalicylate(2) have been synthesized. Crystal structures of the complexes were determined by X-ray diffraction. Crystal 1 belongs to the triclinic space group Pī with a=1.00221(5) nm, b=1.48934(8) nm, c=1.71789(9) nm, α=78.3120(10)°, β=85.6560(10)°, γ=80.2580(10)°, V=2.4725(2) nm3, Z=2, Dc=1.371 g/cm3, μ(Mo)=10.91 cm-1, F(000)=1040, R1=0.0439, wR2=0.1119. Crystal 2 belongs to the monoclinic space group P21/n with a=1.17827(5) nm,b=2.11945(9) nm,c=1.55970(7) nm,β=93.4510(10)°,V=3.8880(3) nm3,Z=4,Dc=1.671 g/cm3,μ(Mo)=14.53 cm-1,F(000)=1936,R1=0.0323,wR2= 0.0927. The tin atoms in complexes 1 and 2 have four coordinates in a distorted tetrahedral configuration and five coordinates in a distorted trigonal bipyramidal configuration, respectively. Further more, the thermal stability and electrochemical and anticancer activity of the complexes were tested. The results show that complexes 1 and 2 are stable below 152 ℃ and below 195 ℃, respectively, and show irreversible redox process. Complexes 1 and 2 display in vitro anti-tumor activity against five human tumor cell lines Colo205, Hep G2, MCF-7, Hela and NCI-H460, and the anti-tumor activity of complex 2 is higher than that of complex 1.
