摘要
以N iC l2.6H2O和4-氰基吡啶为原料,在中温水热反应条件下,合成了一种新型配位聚合物[N i(C6H4NO2)2(H2O)4]n单晶体,并对其进行了元素分析、红外光谱表征和X射线单晶衍射测定。该配位聚合物属三斜晶系,P-1空间群,a=0.6298(4)nm,b=0.6907(4)nm,c=0.9243(5)nm,α=96.437(8),°β=105.184(9)°,γ=113.314(9)°,V=0.3456(3)nm3,Z=2,dc=1.802 g/cm3,μ=1.452mm-1,F(000)=194,R1=0.0309,R2=0.0753。该晶体通过配位键的连接和分子间氢键相互作用形成三维的网状结构。
A novel coordination polymer [ Ni（C6HaNO2）2（H2O）4]n was synthesized by hydrothermal reaction of NiC12 6H20 and 4-cyanopyridine. The structure was characterized by elemental analysis and IR spectroscopy as well as X-ray single crystal diffractometer. The result shows the crystal in monoclinic crystal system and P2 （ 1 ）/c space group, Crystallographic date ： a = 0.6298 （4） nm, b = 0. 6907 （4） nm, c=0.9243（5）nm, α= 96.437（8）°, β= 105. 184（9）°,γ,= 113.314（9）°, V=0.3456（3）nm^3, Z=2, dc =1.802 g/cm^3,μ= 1.452mm^-1, F（000） =194, R1 =0.0309, R2 =0.0753. X-ray analysis reveals that a three- dimensional interpenetrating nets was formed by coordination bonds and hydrogen bonds.
