合成了一维分子梯状配合物{[Cu2(4,4′-bpy)3(p-Ab)2(H2O)2].(NO3)2.4H2O}n(4,4′-bpy=4,4′-联吡啶,p-Ab-=对氨基苯甲酸根离子),该配合物晶体属单斜晶系,P2(1)/c空间群,晶胞参数:a=1.1107(5)nm,b=1.5504(3)nm,c=1.4509(3)nm,β=104.81(3)°,V=2.4155(12)nm3,Z=2.铜离子周围有3个氧原子和3个氮原子与之配位,其中2个氧原子由对氨基苯甲酸的螯合氧原子提供,另一个氧原子由配位水提供,3个氮原子分别由三个4,4′-联吡啶提供.这六个原子在铜离子周围形成一个畸变的八面体配位环境.配体对氨基苯甲酸只有一种配位形式——双齿螯合,第二配体4,4′-联吡啶的两个氮原子均参与配位,将配合物组装成一维分子梯结构.
One-dimensional molecular ladder complex {[Cu2 (4,4’-bpy) 3 (p-Ab) 2 (H2O) 2] (NO3) 2.4H2O} n (4,4’-bpy = Bipyridine, p-Ab- = p-aminobenzoate). The crystal of the complex belongs to the monoclinic space group P2 (1) / c with unit cell parameters a = 1.1107 (5) nm, b = 1.5504 (3) nm, c = 1.4509 (3) nm, β = 104.81 (3) °, V = 2.4155 (12) nm3 and Z = 2. There are three oxygen atoms and three nitrogen atoms around the copper ions Of which two oxygen atoms are provided by the chelating oxygen atom of p-aminobenzoic acid and the other oxygen atom is provided by coordination water and the three nitrogen atoms are respectively provided by three 4,4’-bipyridyls. Atoms form a distorted octahedral coordination environment around the copper ions.The ligand p-aminobenzoate only one coordination form - bidentate chelation, two nitrogen of the second ligand 4,4’-bipyridine The atoms are involved in coordination, the complex assembled into one-dimensional molecular ladder structure.
