摘要
用水热技术合成了配位高聚物[Tb(Hpim)(pim)(phen)]n·1.5nH2O,并通过元素分析、红外光谱和单晶X射线衍射技术确定了其组成和晶体结构.此晶体属三斜晶系,空间群为P墿,晶胞参数a=1.1049(6)nm,b=1.1608(7)nm,c=1.2557(7)nm,α=110.590(9)°,β=99.999(10)°,γ=110.775(8)°;V=1.3252(13)nm3;Z=2;R=0.0492,wR=0.1036.配合物单元通过氢键及邻菲啉之间的芳环堆积效应构筑成纳米链结构并组装成三维超分子结构.
A novel complex \_(n) 1.5nH_(2)O has been prepared by the hydrothermal technique and structurally characterized by elemental analyses, IR spectra and X-ray crystallography. The complex crystallizes in the triclinic system with space group Pī and unit cell parameters a= 1.104 9(6) nm, b=1.160 8(7) nm, c=1.255 7(7) nm,α= 110.590(9)°, β=99.999(10)°, γ=110.775(8)° ; V=1.325 2(13) nm^(3); Z=2; R=0.049 2, wR=0.103 6. One-dimensional nano-chains constructed by coordination bonds are connected into three-dimensional supramolecular network by complicated hydrogen bonding and aromatic stacking interaction between phenanthroline molecules.
