摘要
在甲醇-水混合溶剂中培养得到苯并三氧化呋咱(BTF)的单晶。用红外光谱、核磁共振、质谱以及元素分析等对其结构进行了表征,并采用X-射线单晶衍射测定晶体结构。结果表明,BTF晶体属于正交晶系,P2(1)空间群,晶体学参数为:a=0.6935(12)nm,b=1.9557(3)nm,c=0.6518(11)nm,V=0.884(3)nm3,Z=4,Dc=1.894g/cm3,μ=0.173mm-1,F(000)=504,R1=0.0313,wR2=0.0723。BTF分子的平面性好。
The single crystal of benzotrifuroxan(BTF) was cultured using the mixed solvent of water and methanol.BTF was characterized by using the X-ray single-crystal diffraction analysis,mass spectrometry,nuclear magnetic resonance spectrometry,element analysis and FT-IR technique.The results show that the crystal is orthorhombic system,space group P2(1),with crystal parameters of a=0.6935(12) nm,b=1.9557(3) nm,c=0.6518(11) nm,V=0.884(3) nm3,Z=4,Dc=1.894 g/cm3,μ=0.173 mm-1,F(000)=504,R1=0.0313,wR2=0.0723.The BTF molecule is planar.
