- Abstract
Crystal structures of the macrocyclic TADDOL ( α, α, α′, α′-tetraaryl-1,3-dioxolane-4,5-dimethanol) derivative A and its clathrate with diethyl ether are presented. Both the host and clathrate crystallize in the same space group ( P212121) with very similar cell dimensions, i.e., they are isomorphous. At ambient temperature, diethyl ether escapes from A⋅Et2O, and clathrate single crystals are transformed into the guest-free form without breakdown of the crystal lattice. Conversely, crystalline A, when exposed to Et2O vapor, incorporates guest molecules in a ratio of up to ca. 1 : 1. This behavior, usually the hallmark of inorganic nanoporous materials, allows to describe this compound as an 'organic zeolite'.
