含72元环的二维网状结构超分子配合物的合成与结构

Synthesis and Structure of a 2D Woven Network Structure Supramolecule Complex Containing 72 Membered Macrocycles

用自组装方法合成具有特殊网状结构及光学、电学、磁学、离子或分子交换、催化等性能的化合物的分子工程学和超分子化学近年来成为人们研究的热点，并已取得了很大进展［１，２］．当前常用的一种三角架结构单元是刚性芳基三角架配体［３～５］，而对柔性芳基三角架配体及...

A new flexible aryl heterocyclic tripodal ligand: 1,3,5 tris(imidazol 1 ylmethyl) 2,4,6 trimethylbenzene(titb) was prepared. The titled complex { Cu 3(dien) 3(titb) 2 (ClO 4) 6\5 (CH 3CN) 0.5 (H 2O) 0.25 } n , where dien=diethylenetriamine, was synthesised by two different methods. The complex crystallizes in triclinic system, space group P 1 with a = 1.363 0(3) nm , b =1.583 7(2) nm, c =2.110 5(3) nm, α =70.860(10)°, β =86.700(10)°, γ = 64.900(10)°, V =3.879 7(11) nm 3, Z =2, D c=1.577 g/cm 3, F (000)=1 905, R = 0.058 6 , wR 2= 0 135 9 , S =0.948, Δρ max =1.190×10 3 e/nm 3, Δρ min =-0.472×10 3 e/nm 3. There are two kinds of conformation of the titb ligand in the structure of the titled complex, one is cis, trans, trans conformation, the other is cis, cis, cis conformation. Each Cu(dien) 2+ unit binds with two titb ligands to form a two dimensional woven network structure containing 72 membered macrocycles.
