Synthesis of new 1,2,4-triazolyl containing macrocyclic ligand on the calix[4]arene platform (Schiff base) was performed by condensation of the corresponding upper rim tetra aldehyde derivative of calix[4]arene in 1,3-alternate conformations with 4-amino-4H-1,2,4-triazole. The structure of obtained compound was established by the physical methods (1H, 13C NMR spectroscopies, MALDI mass spectrometry) including single crystal X-ray diffraction. It was found that the cooperation of classical and non-classical hydrogen bonding leads to formation of 1D zigzag supramolecular tubes in the crystalline phase.
