Organic zeolites hydrogen bonds

Multiple hydrogen bonding interactions in tetrahedral building blocks have been employed by the group of Wuest to produce a remarkable tailored porous zeolite mimic, dubbed an organic zeolite because it does not contain any inorganic components at all.104 The pore-forming material is based on... 

Aniline is also able to form hydrogen bonds with inorganic substances. X-ray or neutron diffraction techniques which were applied on absorption products of aromatic hydrocarbon derivatives (benzene, xylenes, mesitylene, aniline, m-nitroaniline, m-dinitrobenzene) and synthetic zeolites Y indicate that the preferred adsorption sites depend on the formation of hydrogen bonds between the organic partner and the framework oxygen164. 

The selective insertion of an oxygen atom into a benzene carbon-hydrogen bond to yield phenol is not a classical organic chemistry reaction. The first process for such a reactions was the Solutia process, based on discoveries by Panov and coworkers at the Boreskov Institute of Catalysis in Novosibirsk and then developed in close cooperation with Monsanto. In this process, the oxidant is nitrous oxide, N2O, while an iron-containing zeolite is used as the catalyst (Equation 13.4) ... 

Bonding between the zeolite lattice and organic molecules adsorbed in the zeolite cavities is best described as a van der Waals-type weak interaction, when interaction solely occurs with the silica zeolite wall. The bonds should be considered to be hydrogen bonds if interaction occurs with the acidic protons bonded to the zeolite framework. The latter type of bond has been discussed in section 4.3. Interaction with the nonframework cations belongs to a category of bonding in between these two extremes.
