    • 2ν symmetry with all four n-propyl groups lying on the same side of the molecule. The aromatic rings A and C are folded "outwards" and inclined by ca. 127°, whilst rings B and D are folded "inwards" and inclined by only ca. 20°. This latter arrangement effectively fills the central cavity of the calix[4]arene, the centroids of rings B and D being separated by only 4.78 Å. The folding of the N,O chelate ring F coupled with the adoption of a δ configuration for the N,N chelate ring results in the C-31 phenyl ring being angled away from the upper face of the calix[4]arene component; the distance of the ortho hydrogen on the C-31 phenyl ring to the hydrogen atom para to the oxygen on ring D (H-23) is 5.16 Å.
