| 摘 要： | 室温下,于CH3OH和H2O的混合溶剂中,钨酸钠存在下邻苯二胺和盐酸反应合成了棕色和红色两种不同颜色的C6H4(NH2)2.2HCl晶体,X-射线单晶衍射分析,晶体属单斜晶系,空间群为C2/c,a=0.7339(2)nm,b=1.4535(5)nm,c=0.8009(3)nm,β=94.041(5)°,V=0.8522(5)nm3,z=4,R1=0.0247,WR2=0.0684。奇特的是棕色晶体与红色晶体均为邻苯二胺盐酸盐,具有相同的晶体结构和IR光谱,但UV光谱呈现出差异。 |

| Abstract: | C6H4(NH2)2·2HCl with red and brown were synthesized at room temperature by the reaction of o-phenylenediamine and hydrochloric in mixed solvent of CH3OH and H2O and the presence of sodium tungstate.Their crystal structures were determined by XRD.The results show that they belong to monoclinic system with the space group C2/c,a=0.733 9(2)nm,b=1.453 5(5)nm,c=0.800 9(3) nm,β=94.041(5)°,V=0.852 2(5) nm3,z=4,R1=0.024 7,WR2=0.068 4.It is fantastic that the crystals with different color have same structure and same IR spectra,but different UV-VIS spectra. |
