Abstract:
In the first part of this investigation (Part I), cone conformers of calix[4]arenes with methylene and heteroatom
bridges from the Cambridge Structural Database (CSD) were investigated. Previously introduced parameters
α, β and δ were utilized in describing the conformations of the hydrocarbon base frame of the above
mentined compounds. In this part of the investigation, partial cone, 1,2- and 1,3-alternate conformers of
methylene- and heteroatom-bridged calix[4]arenes are studied and the influence of inter- and intramolecular
interactions on the conformations of these compounds is evaluated.
