摘要 合成了两个羧酸桥联的铜(Ⅱ)配合物:Cu2(3a-phth)2(bpy)2.CH3OH(1)(3a-phth2-=3-aminophthalate)与[Cu2(3n-phth)2(bpy)2]{Cu(3n-phth)(bpy)}2.H2O(2)(3n-phth2-=3-nitrophthalate),并表征了它们的结构和配合物1的磁性.晶体结构解析结果表明,配合物1中羧基以μ2-O将两个单核铜(Ⅱ)单元桥联形成双核结构,配合物2中除类似的双核结构外,羧基还以三原子桥形式形成一维螺旋链结构.两种亚结构以分子间相互作用形成超分子结构.配合物1中两个铜离子呈铁磁耦合,基于哈密顿算符H∧=-2JS∧Cu1S∧Cu2推导出的磁化率公式与实验数据进行拟和得到磁耦合参数J=0.82(7)cm-1. Two carboxylate-bridged Cu ( I ) complexes, Cu2 (3a-phth) 2(bpy) 2 . CH3OH (1) (3a-phth2- = 3-aminophthalate) and [Cu2 (3n-phth)2 (bpy)2] [Cu (3n-phth) (bpy)]2. H2O (2) (3n-phth2-= 3-nitrophthalate) have been synthesized and characterized structurally and mag- netically. Structural determination shows that complex 1 contains two mononuclear Cu( Ⅱ ) units doubly bridged by twoμ2-O atoms from two carboxylate groups. In complex 2, a Similar dinuclear Cu ( I ) complex and a one-dimensional Cu (I ) helical chain connected by μ1,3-carboxylate groups, form a supramolecular structure via intermolecular interactions. Complex 1 exhibits ferromagnetic properties. On the basis of the Hamiltonian/Q = - 2JScu1Scu2 , the magnetic susceptibilities of complex 1 were fitted giving the magnetic coupling constant of J 0.82(7) cm-1.
