摘要:
The compound of dihydroxglyxime (DHG) was prepared by reaction of hydroxylamine hydro-chloride with diethyl oxalate in ethanol aqueous solution, single crystal of DHG was obtained. The molecular structure was characterized by elemental analysis,IR and single X-ray diffraction analysis. The results show that the crystal belongs to a monoclinic system with Pn space group and cell parameters of a = 0.522 19(15) nm,6-0.387 37(11) nm,c = 1.075 0(3) nm,β = 115. 396(5)°,V = 0.216(ll) nm3, Dc =1.873 g/cm3,Z = 2,F(000) =128,R1 =0.029 8,wR2 =0.079 0.%以盐酸羟胺和草酸二乙酯为原料,在乙醇-水溶液中反应,得到二羟基乙二肟(DHG),培养出该化合物的单晶.并利用元素分析、红外光谱、X射线单晶衍射等方法对该化合物进行了表征.结果表明,该晶体属于单斜晶系,空间群为Pn,晶胞参数a=0.522 19(15)nm,b=0.387 37(11) nm,c=1.075 0(3) nm,β=115.396(5)°,V=0.216(11) nm3,Dc=1.873 g/cm3,Z =2,F(000) =128,R1=0.029 8,wR2=0.079 0.
