Incommensurate suprastructures: new problems of inorganic solid-state chemistry

TEM study of the (SbS)1+(NbS2) , (n=1, 2, 3; δ~1.14, 1.20) misfit layer phases

“…However, in our HRTEM images the rippling of the Q layer was never observed. Another possible explanation can be found in Pervov et al [26,27] where they have predicted theoretically that in a composite crystal structure the fragmentation in domains of one substructure can take place under certain circumstances caused by the interaction with another sublattice with a different unit cell parameter.…”

On Some Problems of Inorganic Supramolecular Chemistry

“…Further studies of supramolecular systems based on layered dichalcogenide matrices with different‐sized guests resulted in the conclusion on the requirement to consider the possibility of self‐organization of incommensurate substructures in such systems. Therefore, the formation conditions and physicochemical properties of so‐called misfit compounds have been studied 6. These host–guest systems attracted our interest for two reasons: first, because of the violation of topological complementarity, and second, because it is impossible to assume a significant change in the charge states of the two partners.…”

“…The results of these works have been summarized in ref. 6. The structures of known misfit compounds are characterized by their incommensurability in one crystallographic direction, thus it was proposed to use a modified classical Frenkel–Kontorova model7 (interacting chains of finite lengths with incommensurate periods) to explain the obtained results.…”

Defects in Lamellar Phases of the Bi$_{2}$Те$_{3}$—Te Eutectics

“…Эвтектические супермолекулярные ансамбли формируются как неавтономные фазы, т.е. фазы, образующиеся вблизи контактной поверхности взаимодействующих субструктур [34][35][36][37].…”
