A novel anionic organotin(Ⅳ) complex {[(pClCHCH)Sn(HO)(Cl)OCOCH(O)CH(O)COSn(HO)(Cl)(p-ClCHCH)]·2(HNEt)}(1) was synthesized by the reaction of di(p-chlorobenzy)tin dichloride with the D-tartaric acid in 2:1 molar...A novel anionic organotin(Ⅳ) complex {[(pClCHCH)Sn(HO)(Cl)OCOCH(O)CH(O)COSn(HO)(Cl)(p-ClCHCH)]·2(HNEt)}(1) was synthesized by the reaction of di(p-chlorobenzy)tin dichloride with the D-tartaric acid in 2:1 molar in the presence of an organic base triethylamine. The structure was characterized by elemental analysis, IR, TG, XRD and single-crystal X-ray diffraction. It crystallizes in triclinic, P1 space group, with a = 0.7067(1), b = 1.9762(3), c = 2.2383(3) nm, α = 91.544(2)°, β = 90.075(2)°, γ = 90.110(2)°, V = 3.1247(7) nm~3, Z = 3, Dc = 1.621 g/cm~3, m(Mo Kα) = 16.29 cm–1, F(000) = 1530, R = 0.0394, wR = 0.1092,(Δρ)max = 1224 and(Δρ)min = –840 e/nm~3. The stabilities, orbital energies and composition characteristics of some frontier molecular orbitals of 1 have been carefully investigated with quantum chemistry calculation. In addition, the in vitro antitumor activity suggested that 1 had stronger inhibitory activity on H460, MCF7 than on A549.展开更多
