7-Deaza-2′-deoxyxanthosine Dihydrate Forms Water-Filled Nanotubes with C−H⋅⋅⋅O Hydrogen Bonds

Abstract

Supramolecular tetrameric aggregates of four molecules of 7-deaza-2′-deoxyxanthosine are stabilized by unconventional C−H⋅⋅⋅O hydrogen bonds. In the solid state the tetramers stack to form a nanotube (see picture), in the center of which water molecules are found which are also stacked.
