2-{[(Pyridin-2-yl)amino]methyl}phenol
Acta Crystallographica Section E, 2012 The planes of the aromatic rings of the title compound, C12H12N2O, are twisted by 50.33 (15)°. The phenol O atom is a hydrogen-bond donor to the pyridine N atom, resulting in the formation of an eight-membered ring in the molecule. The

Nature, 1979 CIRCULAR hydrogen bonds present a new, experimentally demonstrated principle showing how hydration water molecules and hydroxyl groups of macromolecules can cooperate to form a network-like pattern. Quantum chemical calculations show that chain-like H-bonds in the crystal lattice1 are energetically favoured above individual ones2,3.

4-Hydroxy-1-oxo-1,2-dihydrophthalazine-6,7-dicarboxylic acid dihydrate
Acta Crystallographica Section E, 2008 In the crystal structure of the title compound, C10H6N2O6·2H2O, the OH and NH groups each serve as a hydrogen-bond donor to one acceptor site whereas the water molecules each serve as a hydrogen-bond donor to two acceptor sites. The hydrogen-bonding

SOLITONS IN HYDROGEN-BONDED CHAINS
Le Journal de Physique Colloques, 1988 A one dimensional model for hydrogen bonded chains is investigated by including the dynamical degrees of freedom of the oxygens and thus generalizing the original Antonchenko-Davydov-Zolotaryuk model. Analytical solutions are derived within a continuum approximation up to second order so that rather narrow solutions could be derived accurately enough ...
