Abstract: Anew flexible aryl heterocyclic tripodal ligand: 1,3,5-tris(imidazol-1-ylmethyl)-2,4,6-trimethylbenzene(titb) was prepared. The titled complex {Cu3(dien)3(titb)2(ClO4)6?(CH3CN)0.5(H2O)0.25}n , where dien=diethylenetriamine, was synthesised by two different methods. The complex crystallizes in triclinic system, space group P2 with a = 1.3630(3) nm , b =1.5837(2) nm, c =2.1105(3) nm, α =70.860(10)°, β =86.700(10)°, γ = 64.900(10)°, V =3.8797(11) nm3, Z =2, Dc=1.577 g/cm3, F (000)=1905, R = 0.0586 , wR2= 01359 , S =0.948, Δρmax=1.190×103e/nm3, Δρmin=-0.472×103e/nm3. 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.

Key words: Supramolecule, Flexible aromatic tripodal ligand, 72-Membered macrocycles, Two dimensional network woven structure
