摘　　要：合成了 3个三环己基锡 -2 -( 1 ,2 -亚乙二硫 )亚甲基 -3-羰基 -5 -芳基 -4 -戊烯酸酯化合物 .用 IR,1 H NMR,1 3 C NMR和 1 1 9Sn NMR光谱及 X射线衍射对所合成的化合物进行了表征 .结果表明标题化合物为四配位。Three title compounds were prepared and the structure of title compound 2 was characterized by IR, 1H NMR, 13 C NMR, 119 Sn NMR spectroscopy and the crystal structure of compound 2a was determined by X ray analysis with the final R indices[ I>2σ(I)] R 1= 0.035 0 and R 2,ω = 0.088 8. The crystal of compound 2a belongs to triclinic system, space group P1 with a = 1 059 8(6) nm, b = 1 307 4(10) nm, c = 1 378 6(10) nm, α = 62 666 (7)°, β =72 530(2)°, γ =80 680(2)°, V =1 618 0 nm 3, D x=1 444 g·cm -3 , Z=1, F (000)=728. The bond length of Sn1_O1 is 0.207 6 nm and \{Sn1...O2\} distance is 0.301 3 nm. The coordination about the tin atom can be considered as a distorted tetrahedral. The detail values of 1H NMR, 13 C NMR, 119 Sn NMR, 2 J 119 Sn 1H and \%J\% 119 Sn 13 C were obtained. δ 119 Sn = 23.836, 2 J 119 Sn 1H = 88.0 Hz, 1 J 119 Sn 13 C = 347.1 Hz, 2 J 119 Sn 13 C = 45.6 Hz.
