Analysis of Hydrogen Bonds in Crystals - Bog

Crystal structures are a source of information on geometries of species
that form networks in solids, in addition to providing information on the
nature of interactions that occur between them. Hydrogen bonding is one
of the most important interactions responsible for the arrangements of
molecules and ions in crystals. For this reason, this special issue collects
new, interesting, and important findings and ideas on the role of the
hydrogen bond in crystals.
The contributions of this issue may be classified into three groups: the
first concerns new crystal structures where interesting arrangements of
species are described; the second group considers crystal structures and
their observed phenomena; and the last group is strongly related to a
discussion on theoretical results, where often hydrogen bond interactions
are compared with other interactions (halogen bond, pnicogen bond,
carbon bond, etc.).
Despite the fact that the last group of articles concerns the results of
calculations, it is strongly associated with experiment since the results are
compared with experimental observations. Besides other interesting
phenomena, the hydrogen bond interactions are well described in the
theoretical work.
