摘要 合成了一种新的对硝基苯甲醛缩对羟基苯甲酰腙晶体;利用红外光谱、紫外光谱和元素分析对其进行了表征,并利用单晶X射线衍射测定了其晶体结构.结果表明,该晶体属于单斜晶系,P2(1)/n空间群;晶胞参数a=0.766 17(2)nm,b=1.357 3(3)nm,c=1.256 0(3)nm,β=92.71(3)°,V=1.304 7(4)nm3,Z=4,Dc=1.452 g/cm3,μ=0.109 mm-1.12 593个可观察独立衍射点(I>2σ(I))偏离因子R1=0.042 5,wR2=0.142 4,S=1.096. The title compound was synthesized and characterized by means of elemental analysis,infrared spectrometry,ultraviolet-visible light spectrophotometry,and single crystal X-ray diffraction.Results indicate it crystallizes in monoclinic space group P2(1)/n with unit cell parameters of a = 0.766 17(2) nm,b = 1.357 3(3) nm,c = 1.256 0(3) nm,β = 92.71(3)°,V = 1.304 7(4) nm3,Z = 4,Dc = 1.452 g/cm3,μ = 0.109 mm-1.The final R1 =0.042 5,wR2 = 0.142 4,S = 1.096 for 12 593 observed reflections with I 2σ(I).
