摘要
采用溶剂挥发法,选择2-(4-羧基苯基)苯并咪唑为有机配体成功地合成了一种三维层状结构的铜(Ⅱ)配位聚合物,通过X射线单晶衍射仪对结构进行了表征,结果表明,该配合物属于单斜晶系,空间群P21/c,晶胞参数a=0.9939(2)nm,b/=1.0633(2)nm,c=1.5193(3)nm,α=90.00°,β=92.719(4)°,γ=90.00°,Z=2.中心铜原子通过2-(4-羧基苯基)-苯并咪唑配体的两个氧原子和两个氮原子形成平行四边形的配位环境.
A copper( Ⅱ) coordination polymer was successfully synthesized with 4-(1H-benzo[d]imidazol-2-yl)benzoic acid ligand by the solvent evaporation techniques. The crystal structure was determined by X-ray single crystal diffraction.The crystal belongs to monoclinic system and P21/c space group with a= 0.9939(2) nm, b= 1.0633(2) nm, c= 1.5193(3) nm,(3), alpha=90.00°, beta=92.719(4)°, gamma=90.00°, V=1.6038(6)nm3 Z = 2. The copper(Ⅱ) is coordinated with two oxygen atoms and two nitrogen atoms, generating a parallelogram coordination geometry.
