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。
The novel complex {[(n-C4H9) 2Sn (0.5 · O2CC12H10N) (0.5 · CH3O)] 2O} 2 was synthesized by the reaction of N-phenyl anthranilic acid with dibutyltin oxide. Its structure was characterized by elemental analysis, IR and 1H-NMR. The crystal structure of the complex was determined by X-ray single crystal diffraction. The complex crystal belongs to the triclinic system with a space group of P-1 with a = 1.173 (2) nm, b = 1.256 (2) nm and c = 1.329 M = 1.509 mm-1, Dc = 1.425 Mg.m-3, F (000), β = 71.83 (3) °, γ = 65.36 = 736, R = 0.056 9, wR = 0.1589, GOF = 1.074. The test results show that it is centered on the Sn2O2 four-membered ring, the central symmetrical dimer structure. The inner and outer ring tin atoms are five-coordinated distorted triangular double cone configuration.
