| Popis: | The simple triarylmethanol hosts, 2 and 4, and their silicon analogues, I and 3, have been studied for comparison of the formation of crystalline inclusion compounds. Clathrate formation experiments showed that replacement of the carbinol C atoms in 2 and 4 by Si atoms to give I and 3 resulted in a distinct increase of the capability to form inclusion compounds with organic guests, in particular with alcohols. Moreover, the naphthyl derivatives are much more efficient than the phenyl species, irrespective of the carbinol and silanol features. In order to investigate and compare the guest recognition modes and packing relations of hosts 1-4 in their crystalline inclusion compounds, I I selected co-crystals, namely 1-DMSO (2:1), 3-EtOH (1: 1), 3-i-PrOH (1: 1), 3-acetone (1: 1), 3-DMSO (1: 1), 3-THF (1: 1), 3-piperidine (1: 1), 4-acetone (1: 1), 4-DMSO (1: 1), 4-1,4-dioxane (1: 1) and 4-benzene (1: 1), were studied by X-ray diffraction from single crystals. The survey contains additional I I crystal structures from the literature and provides a detailed discussion of isostructurality relationships.
