N2 - The aromatic derivative 2, 8, 14, 20-tert-butylpyrogallol[4]arene was synthesized by the acid catalyzed condensation of pivalaldehyde and pyrogallol in refluxing aqueous ethanol. Single crystal X-ray analysis revealed that the molecule crystallizes in the monoclinic crystal system; space group: P2 1/c. Unit cell dimensions: a = 11.1175(7) Å, α = 90°, b = 23.4525(15) Å, β = 101.6720(10)°, c = 21.9595(14) Å, γ = 90°, Dcalc = 1.205 Mg/m3g/m3 for Z = 4. In the solid state, the macrocycle is found to adopt a crown structure that is unique for the rcct conformation.
