Coordination polymer {[Cu(bpy)(bpe)(NO3)2]·(H2O)4}n (CP1) has been synthesized using [Cu(bpy)(NO3)2] (where bpy = 2,2′-bipyridine) and bpe (bpe = 1,2-bis(4-pyridyl)ethane as a spacer in equimolar ratio. CP1 was characterized by using Infrared spectroscopy, elemental analysis, and single crystal X-ray diffraction. The crystal structure confirms that the CP1 is formed with a bridging bpe linker giving rise to helical chain in one-dimensional (1D) structure. Copper ion is connected to two nitrogen atoms from bpy, two oxygen atoms from nitrate anions (major component) and two nitrogen atoms from two bpe ligands. There is an additional minor component which is five coordinate. The hydrogen bonding links the helical chains to generate a three dimensional (3D) network structure.Graphical abstractA one-dimensional coordination polymer {[(Cu(bpy)(bpe)(NO3)2]·H2O)4}n (CP1) has been synthesized using [Cu(bpy)(NO3)2] (where bpy = 2,2′-bipyridine) as a building block and bpe (bpe = 1,2-bis(4-pyridyl)ethane) as a spacer in a equimolar ratio.

一维自组装配位聚合物，{[Cu(bpy)(bpe)(NO3)2]·(H2O)4}n

已使用 [Cu(bpy)(NO3)2] 合成配位聚合物 {[Cu(bpy)(bpe)(NO3)2]·(H2O)4}n (CP1)（其中 bpy = 2,2'-联吡啶) 和 bpe (bpe = 1,2-双 (4-吡啶基) 乙烷作为等摩尔比的间隔物。使用红外光谱、元素分析和单晶 X 射线衍射表征了 CP1。晶体结构证实了 CP1由桥接 bpe 接头形成，在一维 (1D) 结构中产生螺旋链。铜离子与 bpy 中的两个氮原子、硝酸根阴离子（主要成分）中的两个氧原子和两个 bpe 配体中的两个氮原子相连. 还有一个额外的次要成分，它是五个坐标。氢键连接螺旋链以生成三维 (3D) 网络结构。图形摘要A一维配位聚合物{[(Cu(bpy)(bpe)(NO3)2]·H2O)4}n (CP1)已使用[Cu(bpy)(NO3)2]合成（其中bpy = 2 ,2'-联吡啶）作为结构单元，bpe（bpe = 1,2-双（4-吡啶基）乙烷）作为等摩尔比的间隔基。
