Аннотация:An overview is given of the recent advances in the field of modulated molecular
and inorganic crystals with an emphasis on the links between incommensurability,
intermolecular and interatomic interactions and, wherever possible, the
properties of the materials. The importance of detailed knowledge on the
modulated structure for understanding the crystal chemistry and the functional
properties of modulated phases is shown using selected examples of
incommensurate modulations in organic molecular compounds and inorganic
complex oxides.
