采用水热方法合成出一种新型配位聚合物[Cu(ox)(4,4′-bpy)]n(ox=草酸根离子,4,4′-bpy=4,4′-联吡啶),并通过X射线单晶结构分析、元素分析以及红外光谱测定对该化合物进行了表征.结果表明,标题化合物属于单斜晶系,Cm空间群,晶胞参数a=1·1921(7)nm,b=1·153(7)nm,c=0·5155(4)nm,β=113·38(3)°,V=0·6291(7)nm3,Z=2.该化合物是一个由{Cu(ox)}n链通过桥联配体4,4′-bpy垂直相连并具有矩形格子结构的二维层状配位聚合物,层与层之间交错排列,通过C4,4′-bpy—H…Oox层间氢键作用,进一步扩展成三维超分子网络结构.
A novel coordination polymer [Cu (ox) (4,4’-bpy)] n (ox = oxalate ion, 4,4’-bpy = 4,4’-bipyridine) was synthesized by hydrothermal method. , And the compound was characterized by X-ray single crystal structure analysis, elemental analysis and infrared spectroscopy.The results show that the title compound belongs to the monoclinic system, Cm space group, the unit cell parameters a = 1.1921 (7) nm , b = 1 · 153 (7) nm, c = 0 · 5155 (4) nm, β = 113.38 (3) °, V = 0.6291 (7) nm3 and Z = The {Cu (ox)} n chain is a two-dimensional layered coordination polymer vertically connected by the bridging ligand 4,4’-bpy and has a rectangular lattice structure. The layers are interlaced with each other through the C4,4’- bpy-H ... Oox interlayer hydrogen bonds, further expanding into three-dimensional supramolecular network structure.
