Honeycomb-like layers constructed by hydrogen bonds. Synthesis, structure, and property of two new supramolecular compounds based on polyoxotungstate

Polyanionic clusters embedded in lattice-type hydrogen bonding networks involving in situ bond activation and coupling of organic cations

“…3a). 18 As mentioned above, two chtpy molecules exist in the form of a dimer. Therefore, it can also be seen that the cationic moiety presents a hydrogen bonding double-layered 4-connected sheet through N-H⋯N and O-H⋯O synthons (see Fig.…”
