A view of (II)

, showing part of the atom-labelling scheme. The calixarene numbering scheme starts at the ipso C atom, goes around the C₆ ring, then the ^tBu group and finally the bridging CH₂ unit. Displacement ellipsoids are drawn at the 30% probability level. Only those H atoms involved in hydrogen bonding (indicated by dashed lines) are shown. [Symmetry code: (i) −x + 2, −y + 1, −z + 2.]
