Abstract The title compound was obtained as colourless transparent prismatic crystals (from acetone/methanol 1:1), space groupPīa=16.647(2),b=16.447(2),c=14.269(3) Å, α=108.56(3), β=105.63(3), γ=87.23(3)°,Z=1,D calc=1.03 g cm−3. Refinement was carried out using 2863 reflections, withI〉σ(I). The molecule, which lies on a center of symmetry, possesses a roughly ellipsoidal shape with two sets of four phenolic nuclei following a helical arrangement. The polyether chains of two adjacent phenolic units partially fill the intramolecular cavity. No guest molecules are present.
