合成了一个新颖的一维Cu(Ⅱ)配位聚合物{[Cu(L)(4,4′-bpy)]·ClO_4}_n[L=N-(2-羟乙基)水杨醛亚胺,bpy=4,4′-联吡啶].X-射线单晶衍射结果表明,该配合物属正交晶系,Pbcn(60)空间群,晶胞参数a= 1.316 48(19)nm,b=1.219 52(17)nm,c=2.503 7(4)nm.配体N-(2-羟乙基)水杨醛亚胺以三齿方式配位,其配位原子包括酚羟基氧原子,醇羟基氧原子和亚胺基氮原子.在[Cu(L)(bpy)]·ClO_4单元中,4,4′-联吡啶作为桥联配体,联接相邻单元中的Cu(Ⅱ)离子,形成一维Zig-Zag链状结构.变温磁化率测定结果表明,在配合物中,通过4,4′-联吡啶联接的Cu(Ⅱ)离子之间存在弱铁磁偶合作用.
A novel one-dimensional Cu (Ⅱ) coordination polymer [Cu (L) (4,4’-bpy)] · ClO_4} _n [L = N- bpy = 4,4’-bipyridyl] .The results of X-ray single crystal diffraction show that the complex belongs to the orthorhombic system and the space group Pbcn (60) has a unit cell parameter of a = 1.31648 (19) nm and b = 1.219 52 (17) nm, c = 2.503 7 (4) nm. The ligand N- (2-hydroxyethyl) salicylaldimine is coordinated in a tridentate manner and its coordinating atoms include phenolic hydroxyl oxygen atoms, Atom and imino nitrogen atom. In [Cu (L) (bpy)] · ClO_4 unit, 4,4’-dipyridyl acts as bridging ligand to couple Cu (Ⅱ) ions in adjacent units to form a Dimensional Zig-Zag chain structure.The results of temperature-dependent magnetic susceptibility show that there is a weak ferromagnetic coupling between the Cu (Ⅱ) ions bound by 4,4’-dipyridyl in the complex.
