摘　　要：以乙酰二茂铁和氨基三氮唑为原料：合成了两种新型的二茂铁三氮唑Schiff碱化合物，其结构通过IR，^1H—NMR，元素分析和X-射线单晶衍射法确定。X射线单晶结构分析表明，固态时化合物1a与-分子水通过分子间氢键形成-维无限链状结构，其晶体属单斜晶系，P21／n空间群，Mr：312．16，a=11．679（2），b=9．862（2），c=12．717（3）A，β=108．60（3）°k，v=1388．3（5）A，Z=4，Dc=1．493mg·m^-3，μ=n71073A，F（ooo）=648，最终偏离因子R=0．0454，wR=0．0984。电化学分析表明1a和1b的电化学性质相似，在电位0．4—1．1V范围内，都只有一对氧化-还原峰，对应于Fc／Fc^＋电对，且该过程是受扩散控制的可逆过程。Two novel Schiff base compounds bearing ferrocene and triazole（ { 1 - [ （4H - 1,2,4 - triazol -4 - yl）imino ] ethyl } ferrocene （ 1 a） and { 1 - [ （ 3,5 - dimethyl - 4H - 1,2,4 - triazol - 4 - yl） imino] ethyl } ferrocene （ 1 b） ） were synthesized by the condensation reactions of acetylferrecene with amino - triazole. The structures of the compounds were determined by IR, ^1H - NMR spectra ,elemental analysis and single crystal X - ray diffraction. X - ray analysis revealed that compound la has an one - dimensional chain structure, which is formed by intermolecular hydrogen bonds between compound 1 a and water in solid state. The crystal was monoclinic system,space group P2 1/n,Mr：312.16,a = 11. 679（2） ,b =9. 862（2） ,c = 12.717（3） -A,β = 108. 60（3）° ,V = 1388. 3（5）.A^3,z =4,Dc = 1. 493 mg· m^-3,μ =0. 71073.A,F（000） = 648,R =0. 0454,wR =0. 0984. It was found that the elec- trechemical property of 1 a was very similar to 1 b, showing one pair of well - defined and stable redox waves in the potential range of 0. 4 - 1.1 V at the GC electrode,which is attributed to the Fc/Fc^＋ redox process. The process was confirmed as a reversible ,diffusion - controlled one.
