摘要
合成了一种新颖的配合物[Zn(H2O)6](NO2-C9H4O6)2.4H2O,并用X–射线单晶衍射仪测定了其结构.晶体数据表明,该配合物属三斜晶系,P-1空间群,晶胞参数为:a=6.850(19),b=6.92(2),c=19.25(6),α=92.74(5)°,β=92.10(5)°,γ=118.13(3)°,V=802(4)3,Z=1,Dcalc=1.562g.cm-3,μ=0.869 mm-1,F(000)=388,R1=0.0787,wR2=0.2106.在配合物结构单元中,Zn原子与六个水分子配位,形成略有畸变的八面体阳离子基团,阳离子基团和5–硝基–1,2,3–苯三甲酸负一价阴离子通过氢键相互作用连接在一起形成二维三明治状超分子化合物.
A new coordination compound [Zn（H2O）6] （ NO2-C9H406 ） 2·4H2O has been synthesized. The crystal structure of the compound was determined by X-ray single crystal diffraction. As the data indicate, its crystal belongs to triclinic system with space group P-l, a =6. 850（ 19）A,b =6.92（2）A,c = 19.25（6）A,α= 92.74 （5）°, β = 92.10（5）°, γ= 118.13（3）°,V= 802（4）A3,Z=1,Dcalc =1.562 g·cm-3,μ = 0.869 mm-1,F （000） = 388 ,R1 = 0.0787, wR2 = 0. 21060 In the compound, Zn atom is six-coordinated by six oxygen atoms of coordinated-water. The packing of the molecules is mainly a result of hydrogen bonds interactions, resulting in a two-dimensional polymer structure.
