摘要
以1,10-邻菲咯啉取代的半苷脲盐酸盐为原料,在水溶液中与AgNO3反应,生成了配位聚合物AgLNO3.X-射线单晶衍射表明:该配位聚合物属单斜晶系、P2l/c空间群,晶胞参数:a=1.11718(7)nm,b=1.037 03(7)nm,c=1.105 81(7)nm,β=111.956(2)°,V=1.18822 nm-3,Z=14,Dc=2.952 g/cm3,μ=5.684 mm-1,F(000)=966,R1[I>2σ(I)]=0.032 0,wR2[I(2σ(I)]=0.0873.该配位聚合物以中心离子银(Ⅰ)与1,10-邻菲咯啉环上的两个氮原子和硝酸根的一个氧原子形成三配位的不等边三角形,配合物分子间通过C—H…O氢键作用形成了平面网状结构,这些平面网状结构之间再通过π…π堆积作用形成了三维网状结构.
The compound AgLNO3[L=1,10-Phenanthroline-5,6-dione(PhenDO)] have been synthesized with 3a,11b-Dihydroxy-2-oxo-2,3,3a,11b-tetrahydro-1H-imidazo[4,5-f][1,10] phenanth-roline-7-ium-chloride(DHphen) and AgNO3 in aqueous solution.The experimental result of X-ray single crystal diffraction analysis revealed that the title compound has a monoclinic space group P2l/c,with a=1.117 18(7) nm,b=1.037 03(7) nm,c=1.105 81(7) nm,β=111.956(2)°,V=1.188 22 nm-3,Z=14,Dc=2.952 g/cm3,μ=5.684 mm-1,F(000)=966.The final R1=0.032 0 and wR2=0.087 3.The silver(Ⅰ) center is three-coordinated and surrounded by one oxygen atom from nitrate and two nitrogen atoms from PhenDO,giving a distorted plane triangle coordination geometry.The crystal structure of complex forms metalorganic supramolecular frameworks by C-H…O and π…π stacking.
