摘要
A new calix[4]arene derivative, 5,11,17,23 tetra tert butyl 25,27 dihydroxy 26,28 bis[2 (methoxycarbonyl)benzyloxy]calix[4]arene was synthesized. The X ray crystal structure of the title compound has been determined. It crystallizes in the monoclinic with space group C2/c, a = 1.262 8(3) nm , b = 2.535 0(5) nm, c = 2.095 7(4) nm, β = 103.36 (3)°, V = 6.528(2) nm 3, Z =4, D c= 1.203 g/cm 3, \{ F (000)=2 488, R = 0.114 3 , wR 2 = 0.297 9, Δ ρ max = 0.329× 10 3 e/nm 3, Δ ρ min = -0.256× 10 3 e/nm 3. The crystal structure of the title compound shows that in the molecule there are hydrogen bonds between proximal hydroxyl and ether functional groups [O(H)—O: 0.300 4 nm ]. The benzoic ether site in the title molecule may be considered as a π conjugated system, therefore, the intermolecular π π interaction exists between two benzoic ether site of the adjacent molecules, which caused the formation of a one dimensional saw toothed supramolecule.
