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 novel complex [Zn (H2O) 6] (NO2-C9H4O6) 2.4H2O was synthesized and its structure was determined by X-ray single crystal diffractometry.The crystal data showed that the complex belongs to triclinic system and P -1 space group with unit cell parameters of a = 6.850 (19) , b = 6.92 (2) and c = 19.25 (6) with α = 92.74 (5) ° and β = 92.10 γ = 118.13 (3) °, V = 802 (4) 3, Z = 1, Dcalc = 1.562 g · cm -3, μ = 0.869 mm -1, F (000) = 388, 0.2106. In the complex structure units, Zn atoms coordinated with six water molecules to form slightly distorted octahedral cationic groups, the negative of the cationic groups and 5-nitro-1,2,3-benzenetricarboxylic acid Valence anions are linked together by hydrogen bonding to form a two-dimensional sandwich-like supramolecular compound.
