Abstract: Anew 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=1.2628(3) nm, b=2.5350(5) nm, c=2.0957(4) nm, β=103.36 (3)°, V=6.528(2) nm3, Z=4, Dc=1.203 g/cm3, F (000)=2488, R=0.1143, wR2=0.2979, Δ ρmax=0.329× 103 e/nm3, Δ ρmin=-0.256× 103 e/nm3. 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: 0.3004 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.

Key words: Calix[4]arene, Crystal structure, Intermolecular π-&pi, interaction, Supramolecule
