Notes: Abstract p-tert-Butylcalix[6]arene forms a complex with 1.5 acetonitrile molecules, that are included in the macrocycle cavity. This complex crystallizes in the monoclinic system: space groupP21/m,a=14.043(4),b=16.916(11),c=14.199(11) Å,β=98.27(6)°,V=3338(4) Å3,Z=2 (formula units). Refinement led to a final conventionalR value of 0.113 for 1654 reflections. Thepinched cone conformation of the calixarene is the same as that of the neutral and freeR-calix[6]arene already described. The two acetonitrile molecules interact with some phenyl ring π-clouds, a methylene bridge and sometert-butyl groups of the calixarene.
