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.
