摘　　要： 利用二烃基氧化锡和α-萘氧乙酸按1∶1反应,合成了8种新的有机锡化合物,｛[R2Sn(OOCCH2OC10H7)]2O｝2(R=nBu1,2-ClC6H4CH22,3-ClC6H4CH23,4-ClC6H4CH24,2-FC6H4CH25,3-FC6H4CH26,4-FC6H4CH27,4-NCC6H4CH28)。用元素分析、IR、1HNMR对其结构进行了表征,并测定了化合物｛[nBu2Sn(OOCCH2OC10H7)]2O｝2(1)的晶体结构。该化合物晶体属三斜晶系,空间群P1,a=11.974(7)nm,b=1.3605(9)nm,c=1.3865(9)nm,α=103.940(9)°,β=104.876(8)°,γ=99.807(9)°,Z=1,V=2.053(2)nm3,Dc=1.431Mg·m-3,μ=1.261mm-1,F(000)=900,S=1.004,R1=0.0610,wR2=0.1519。结果表明,化合物1是以Sn2O2为中心的中心对称二聚体结构,内环锡和外环锡原子均为五配位的畸变三角双锥构型。 The eight new organotin compounds, [[R2Sn（OOCCH2OC10H7）]2O}2（R=^nBu1,2-ClC6H4CH22,3-ClC6H4CH23,4-ClC6H4CH24,2-FC6H4CH25,3-FC6H4CH26,4-FC6H4CH27,4-NCC6H4CH28）, were synthesized by the reaction of dialkyltin oxide with α-naphthyloxyacetic acid in 1：1 molar ratio. All compounds are characterized by elemental analysis, IR, ^1H and U9Sn NMR spectra, and compound {[^nBu2Sn（OOCCH20C10H7）O}2（1） has been determined by X-ray single crystal diffraction. The crystal belongs to triclinic with space group P1, a=11.974（7） nm, b=1.360 5（9） nm, c=1.386 5（9） nm, α=103.940（9）°, β=104.876（8）°, γ=99.807（9）°, Z=1, V=2.053（2） nm^3, Dc= 1.431 Mg·m^-3,μ=1.261 mm^-1, F（000）=900, S=1.004, R1=0.061 0, wR2=0.151 9. The compound 1 belongs to centrosymmetric dimer structure mode with a four-membered central endo-cyclic Sn2O2 unit in which the bridged oxygen atoms are tri-coordinated. Each bridged oxygen atom also connects with an exo-cyclic tin atom. Both endo-cyclic and exo-cyclic tin atoms are five-coordinated and have coordination geometry of distorted trigonal bipyramid.
