由2-(2-羧基苯基)-苯并咪唑和二正丁基氧化锡反应,制得新化合物{[(n-C4H9)2Sn(0.5·O2CC13H9N2)(0.5CH3O)]2O}2.通过元素分析、红外光谱等对其结构进行了表征,用X-射线单晶衍射仪测定了配合物的晶体结构.该配合物属于三斜晶系,空间群为P-1,晶胞参数a=1.0815(4)nm,b=1.2481(4)nm,c=1.3292(4)nm,α=83.502(5)°,β=86.049(5)°,γ=78.631(5)°,V=1.7457(10)nm3.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 new compound {[(n-C4H9) 2Sn (0.5 · O2CC13H9N2) (0.5CH3O)] 2O} 2 was prepared by the reaction of 2- (2-carboxyphenyl) -benzimidazole with di- The crystal structure of the complex was characterized by elemental analysis, infrared spectroscopy and X-ray single crystal diffraction.The crystal belongs to triclinic system with space group P-1, unit cell parameter a = A = 83.502 (5) °, β = 86.049 (5) °, γ = 78.631 (5) °, V = 1.7457 (4) nm, b = 1.2481 10) nm3. The experimental results show that it is a centrally symmetric dimeric structure centered on the Sn2O2 four-membered ring, and the inner and outer ring tin atoms are all five-coordinated distorted triangular double cones.
