室温下由2,3-二甲氧基苯甲醛、4-硝基苯胺缩合反应制成了N-(2,3-二甲氧基苯基亚甲基)-4-硝基苯胺(1)。X射线单晶衍射仪测定了(1)的晶体结构,属于单斜晶系,P2(1)/c空间群,晶胞参数为:a=1.41919(14)nm,b=1.39745(12)nm,c=0.69710(7)nm,α=90°,β=102.365(1)°,γ=90°,V=1.3505(2)nm3,F(000)=600,Mr=286.28,Dc=1.408 g/cm3,μ=0.104 mm-1,R1=0.1138,ωR2=0.2621。 N- (2,3-dimethoxyphenylmethylene) -4-nitroaniline (1) was prepared from the condensation of 2,3-dimethoxybenzaldehyde and 4-nitroaniline at room temperature . The crystal structure of (1) was determined by X-ray single crystal diffraction and belongs to the monoclinic space group P2 (1) / c with unit cell parameters of a = 1.41919 (14) nm and b = 1.39745 , c = 0.69710 (7) nm, α = 90 °, β = 102.365 (1) °, γ = 90 °, V = 1.3505 (2) nm3, F (000) = 600, Mr = 286.28, Dc = 1.408 g /cm3,μ=0.104 mm-1, R1 = 0.1138, ωR2 = 0.2621.
