N2 - The aromatic derivative 2,8,14,20-tetranaphthylpyrogallol[4]arene was synthesized by the acid catalyzed condensation of 2-naphthaldehyde and pyrogallol in refluxing aqueous ethanol. Single crystal X-ray analysis revealed that the molecule crystallizes in a triclinic space group P1(bar) No. 2, with a=11.3396(7) Å, b=15.9942(10) Å, c=26.3653(17) Å, α=94.309(2)°, β=91.765(2)°, γ=93.892(2)°, D calc=1.298 g/m 3 for Z=1. Within the unit cell, six methanol molecules of crystallization plus one molecule of pyrazine were found to accompany the pyrogallol macrocycle. In the solid state, the macrocycle is found to adopt the chair conformation.
