Crystal structures are a source of information on geometries of speciesthat form networks in solids, in addition to providing information on thenature of interactions that occur between them. Hydrogen bonding is oneof the most important interactions responsible for the arrangements ofmolecules and ions in crystals. For this reason, this special issue collectsnew, interesting, and important findings and ideas on the role of thehydrogen bond in crystals.The contributions of this issue may be classified into three groups: thefirst concerns new crystal structures where interesting arrangements ofspecies are described; the second group considers crystal structures andtheir observed phenomena; and the last group is strongly related to adiscussion on theoretical results, where often hydrogen bond interactionsare compared with other interactions (halogen bond, pnicogen bond,carbon bond, etc.).Despite the fact that the last group of articles concerns the results ofcalculations, it is strongly associated with experiment since the results arecompared with experimental observations. Besides other interestingphenomena, the hydrogen bond interactions are well described in thetheoretical work.
