摘要 以2,4,6-吡啶三甲酸(H3ptc)和六水合高氯酸镍为原料用水热方法合成了三维超分子配合物[Ni(H2O)6]1.5.[Ni(ptc)(Hptc)].(H2O)4,并经X射线衍射分析确定了其单晶结构.该晶体属三斜晶系,P墿空间群,晶胞参数为:a=1.03058(16)nm,b=1.11852(17)nm,c=1.4689(2)nm,α=74.725(2)°,β=77.777(2)°,γ=64.734(2)°,V=1.4675(4)nm3,Mr=798.20,Z=2,ρ=1.806g/cm3,F(000)=822,μ=1.701mm-1,R1=0.0373,wR2=0.0993.结果表明,在组成该超分子体系的基本结构单元[Ni(ptc)(Hptc)]3-和[Ni(H2O)6]2+中,Ni(Ⅱ)离子均处于变形八面体配位环境中.配合物单元之间通过氢键相互连接,形成了无限延伸的三维超分子网状结构. A supermolecular compound [ Ni( H2 O) 6] 1.5· [ Ni(ptc) (Hptc) ] · ( H2 O) 4 was synthesized with pyridine-2, 4, 6-tricarboxylic acid( H3ptc) and Ni(C1O4) 2· 6H2O, and its structure was determined by single-crystal X-ray diffraction. The crystal belongs to triclinic system with Pi space group. The cell parameters are: a = 1.030 58(16) nm, b = 1. 118 52(17) nm, c = 1.468 9(2) nm , α = 74.725(2)°, β=77.777(2)°, γ=64.734(2)°, V=1.4675(4) nm^3, Mr=798.20, Z=2, p= 1. 806 g/cm^3, F(000) =822, μ = 1. 701 mm^-1, R1 =0. 373, ωR2 =0. 099 3. The crystal structure consists of [ Ni(ptc) (Hptc) ] and [ Ni( H2O) 6] units in which Ni( Ⅱ ) ions are all located in distorted octahedral centers. Complex molecules are linked by extensive hydrogen bonds, forming a three-dimentional supramolecular structure.
