摘　　要：合成Schiff碱N-氧化吡啶-2-甲醛缩α-氨基苯乙酮并获得其单晶结构.用UV-Vis和IR谱进行表征.其分子式为:C14H12N2O2,Mr=241.26,晶体属于单斜晶系,空间群P21/n,晶胞参数:a=0.81496(11)nm,b=1.556 20(2)nm,c=0.954 60(14)nm,β=105.607(3)°,V=1.16600(3)nm3,Z=4,Dc=1.374 g/cm3,μ=0.094mm-1,F(000)=508,结构偏离因子R1=0.0734,wR2=0.2256.X-射线分析显示Schiff碱的晶体结构是由d…π和π…π相互作用堆积而成的三维结构.The crystal structure of the title Schiff base derived from picolinadehyde N-oxide and α-aminophenylethanone was determined by single crystal X-ray diffraction method and characterized by UV and IR spectra. The main crystallographic datas are as follows： C14H12N2O2, Mr=241.26, monoclinic, space group P21/ n, a=0.814 96（11）nm,b=1.556 20（2）nm,c=0.954 60（14）nm,β=105.607（3）°,V=l.16600（3）nm^3,Z=4,Dc= 1.374 g/cm^3,μ=0.094 mm^-1,F（000）= 508, R1=0.073 4, wR2=0.225 6. The X-ray analysis reveals that the crystal structure of the Schiff base is 3-D structure through d…π and π…π stacking interactions.
