A crystal of the exocavity complex of p-Tert-butylthiacalixarene (2) with diethylamine (2·Et2NH) includes alkanes that cannot be included in a crystal of compound 2 alone and produces two types of inclusion crystals. X-ray crystallographic analysis of inclusion crystals 2·Et2NH·(hexane)0.5 and 2·(Et2NH)1.5·(heptane)0.5·H2O, which were chosen as representatives of the two types, reveals that hexane and heptane are captured in a space surrounded by four self-inclusion dimers of the exocavity complex and in a capsule constructed by two exocavity complexes, respectively. The crystal of 2·Et2NH selectively includes hexane, heptane, and octane from mixtures with their branched isomers.
