The pentahydroxy-p-tert-butylcalix[5]arene, 5,11,17,-\ud23,29-penta-tert-butylhexacyclo[25.3.1.13,7.19,13.115,19._\ud121,25 ] pentatriaconta- 1 (31),3,5,7 (35),9,11,13(34), 15,17,-\ud19(33),21,23,25 (32),27,29-pentadecaene-31,32,3 3,34,-\ud35-pentaol-n-hexane (1/0.3), C55H70Os.0.3C6HI4 (I),\udadopts an open distorted chalice-shaped conformation in\udthe solid state, primarily through O--H...O intramolecular\udhydrogen bonding involving all of the aromatic hydroxyl\udgroups. The five phenolic O.- .O separations are in\udthe range 2.735 (7)-2.880 (8) ,~ [mean 2.793 (8) ,4,], with\udall hydroxyl H atoms disordered equally over two sites.\udThe aromatic rings are tilted back from the calixarene\udcavity producing a pentagonal-shaped cavity in which the\udtert-butyl group of a neighboring calix[5]arene related by\uda c-glide is enclathrated. This self-inclusion process extends through the lattice as a one-dimensional molecular\ud'zipper'
