摘要
以N-苯基邻氨基苯甲酸与二丁基氧化锡反应,制得新配合物{[(n-C4H9)2Sn(0.5·O2CC12H10N)(0.5·CH3O)]2O}2。通过元素分析、红外光谱和核磁共振氢谱对其结构进行了表征,用X-射线单晶衍射测定了配合物的晶体结构。该配合物晶体属于三斜晶系,空间群为P-1,晶胞参数a=1.173(2)nm,b=1.256(2)nm,c=1.329(2)nm,α=82.29(3)°,β=71.83(3)°,γ=65.36(3)°,V=1.690(5)nm3,Z=1,μ=1.509 mm-1,Dc=1.425 Mg.m-3,F(000)=736,R=0.056 9,wR=0.1589,GOF=1.074。测试结果表明,它是以Sn2O2四元环为中心,中心对称的二聚体结构。内、外环锡原子均为五配位的畸变三角双锥构型。
Organotin（Ⅳ） compound {[（n-C4H9）2Sn（0.5·O2CC12H10N）（0.5·CH3O）]2O}2 was synthesized by the reaction of n-dibutyltin oxide with N-phenylanthranilic acid.The compound was characterized by elemental analysis,IR and 1H NMR analyses.The crystal structure was determined by X-ray single crystal diffraction method.The result indicates that crystal belongs to triclinic,space group P-1 with a =1.173（2） nm,b = 1.256（2） nm,c= 1.329（2） nm,α = 82.29（3）°,β = 71.83（3）°,γ = 65.36（3）°,V = 1.690（5） nm3,Z = 1,μ= 1.509 mm-1,Dc = 1.425 Mg·m-3,F（000） =736,R = 0.056 9,wR = 0.158 9,GOF = 1.074.The complex is a centrosymmetric structure mode with a four-member central endo-cyclic Sn2O2 unit in which two bridged oxygen atoms both connect with an exo-cyclic tin atom.The endo-cyclic tin atoms and the exo-cyclic tin atoms are all five-coordination and have coordination geometry of distorted trigonal bipyramid.
