Abstract
Molecular and crystal structures of four lower rim substituted tert-butyl-thiacalix[4]arenes are studied. It is shown that the cone conformation of the macrocycle can be regulated by the number, type, attachment point, and the size of substituents at the lower rim. Isomers with the 1,3-alternate macrocycle conformation are most preferable due to large substituents.
