【摘要】通过2,4-二硝基咪唑(2,4-DNI)的钠盐水溶液与硝酸铅的水溶液反应,制备出了2,4-二硝基咪唑铅配合物;采用自然挥发法培养出了适于X光结构测定的单晶,X射线衍射测定结果为,晶体属单斜晶系,空间群为Cc,晶体学参数为:a=6.517(3)×10-1nm,b=17.131(6)×10-1nm,c=14.082(7)×10-1nm,α=90.00(3)°,β=97.80(4)°,γ=90.00(4)°,V=1 557.5(12)×10-3nm3,Z=4,Dc=2.531 g/cm3,μ=11.001 mm-1,F(000)=1 120,最后偏离因子R为0.022 6。根据红外光谱、元素分析和X射线衍射分析结果,确定了2,4-二硝基咪唑铅配合物的化学组成为C6H10O12N8Pb,分子结构式为[Pb(DNI)2(H2O)4]。更多还原

【Abstract】 [Pb(DNI)2(H2O)4] was prepared by mixing the aqueous solution of sodium 2,4-dinitroimidazolate and lead nitrate.The single crystal structure of [Pb(DNI)2(H2O)4] has been determined by single crystal diffraction analysis.The crystal monoclinic space group Cc with crystal parameters of a=6.517(3)×10-1 nm,b=17.131(6) ×10-1 nm,c=14.082(7)×10-1 nm,α= 90.00(3) °,β=97.80(4)°,γ=90.00(4) °,V=1 557.5(12)×10-3 nm3,Z=4,Dc=2.531 g/cm-3,μ=11.001 mm-1,F(000)=1 120.The final deviation factor R is 0.022 6.According to the IR spectra analysis,the element analysis and the X-ray diffraction analysis,the chemical component of the 2,4-DNI lead complex is C6H10O12N8Pb and its formula is [Pb(DNI)2(H2O)4].更多还原
