Oxygen bonding with hydrogen

The oxygen atoms extend between Na+ ions, providing some shielding. The N atoms (of NHj) extend upward in the figure forming three equivalent hydrogen bonds with oxygen atoms of three other anions. 

Hydrogen bonds with oxygen groups of silicates... 

The several hydroxyl groups that are attached to the cellulose chain form hydrogen bonds with oxygen atoms of adjacent polymer chains, linking the cellulose molecules together side-by-side and forming monocrystalline microfibrils. These self-assembled objects are insoluble in water and form a network inside the plant cell walls [5]. 

Figure 2.15 The organic-inorganic interface, (a) R—NH3" " head groups form hydrogen bonds with oxygen on the silicate surface. The average O - H distance is approximately 150 pm and the mean N to O distance is 245 pm. (b) R—N(CH3)3" head groups do not...

These equilibria could be qualitatively confirmed by the different kinds of experiments [33, 34]. The protons thus formed is considered to be hydrogen bonding with oxygen ions in the lattice and sometimes the proton is written as...
