Solid hydrate research of the last fifteen years is critically evaluated with regard to bonding
and structure of water molecules. This review focusses on new results of structure …

Recent developments in various areas of chemistry have been decisively influenced by the
principles of structure and mechanism and by the ideas of coordination chemistry, in …

The asymmetry of hydrogen bonds arises from the repulsion between the O atoms forming
the bonds. A bond-valence analysis of the repulsion leads to the conclusion that strong and …

The first paper on librational modes (LMs) of water in hydrated solids appeared in 1956 [l],
although some earlier papers mentioned them in the context of other studies [2–4]. No …

An empirical energy function designed to calculate theinteraction energy of a chemical
probe group, such as a carbonyl oxygen or an amine nitrogen atom, with a target molecule …

In designing a therapeutic agent based on the threedimensional structure of a target
receptor molecule, it is necessary to be able to predict where it will bind to the target and …

A survey of the geometry and environment of water molecules in crystalline hydrates is
presented. Histo-grams and correlation analyses are based on 97 crystal structures …

An analysis of the geometries of one hundred OH⋯ O hydrogen bonds observed by neutron
diffraction in 24 crystal structures shows the following results. Twenty-Five of the hydrogen …

Hydrogen plays an extremely important role in the structure and chemistry of the oxide and
oxysalt minerals. The characteristics of this role can be profitably analyzed in a simple and …

IN recent studies of the non-linearity of hydrogen bonds1, 2, histograms have been shown of
the O–H⋯ O angles, ψ The distributions reflect the energy dependence of the hydrogen …
