In the solid state, tris(alkylamido) derivatives OP(NHMe)3 and OP(NHBu )3 form supramolecular architectures through hydrogen bond self-assembly. Lithiation of OP(NHR)3 and SP(NHR)3 also yields self-assembled structures, formed through Li and Li S interactions. ... 

Hydrogen-bond self-assembly may lead to formation of carbon-free cychc sttuctures containing oxygen and hydrogen in a ring, such as tetrameric [Ph3SiOH]4 or more complex cyclic sttuctures such as dimeric...

Diorganosilanediols, R2Si(OH)2, participate in hydrogen-bonding self-assembly with two Si-OH groups, and give rise to quasi-cyclic dimeric, 6, or tetrameric, 7, supermolecules, or single and double chain-like supramolecular arrays, 8-10. 

Rather similar hydrogen-bond self-assembly is observed in another polymeric five-coordinate trimethyltin cyanamidosulfonate hydrate, 4-MeC6H4S02NCNSnMe3, 26, investigated by X-ray diffraction [59]. 

The presence of water in organometallic crystal hydrates is almost certain to produce hydrogen-bond self-assembly with formation of supramolecular structures.

The second use of hydrogen bonding to tune aromatic stacking interactions can be best explained by the relative lack of directionality associated with the r-stacking interaction. The last example in the previous section shows that, despite the introduction of four aromatic stacking interactions at the periphery of linear hydrogen-bonded self-assembled structures, no major perturbations affect...
