“…IN INORGANIC SYSTEMS The supramolecular model of eutectics and mech anisms of the formation of nonautonomous phases in inorganic systems, which were proposed by us earlier [47,48], agree well with the above described effect of increase in the transport characteristics at intergrain and interphase boundaries. The model allows us to predict the possibilities of formation of amorphized structures depending on incommensurability and the potential of interaction between the components.…”

New possibilities to improve the transport characteristics of ceramic electrode materials, which are important for improvement high energy electrochemical devices, lithium-ion batteries (LIBs), and solid oxide fuel cells (SOFCs), have been determined. Since the full scale search for new electrochemically active inorganic structures does not promise substantial progress, it is topical to use the possibilities associated with optimizing the structural parameters of already known materials. It is shown that an enhancement in the spe cific power of these devices associated with an increase in the ionic conductivity of electrode materials can be achieved at the expense of a combination of size effects and experimentally proven effects of amorphization, i.e., the effects of nonautonomic phases formed on the interfaces of composites from incommensurate struc tural elements. They can provide a substantial increase in the diffusion mobility of lithium and oxygen ions at intergrain and interphase boundaries. Simple experimental methods to obtain such multi structured nano materials based on electrochemically active phases for LIB positive electrodes are proposed.

“…This inconsistency in the provided results is evidently associated with the complexity of the processes occurring at the interfaces. In [50], the authors delve into the relationship between the presence and interaction of defects at incommensurate interfaces with low-melting fusibility (leading to the formation of eutectic non-autonomous phases). This phenomenon can be attributed to the significant weakening of bonds within interacting substructures.…”

All-solid-state batteries (ASSBs) are the important attributes of the forthcoming technologies for electrochemical energy storage. A key element of ASSBs is the solid electrolyte materials. Garnets are considered promising candidates for solid electrolytes of ASSBs due to their chemical stability with Li metal anodes, reasonable kinetic characteristics (σLi∼ 10−3–10−4 S · cm−1) and a wide electrochemical window. This study is aimed at the analysis of the experimental data available for garnet thin films, examining the ionic conductivity through the film/substrate lattice mismatch, the elastic properties and the difference in the thermal expansion characteristics of the film and the substrate, the deposition temperature of the film, and the melting point and the dielectric constant of the substrate. Based on the results of this analysis and by introducing the corresponding characteristics involved as the descriptors, the quantitative models for predicting the ionic conductivity values were developed. Some important characteristic features for ion transport in garnet films, which are primarily concerned with the film/substrate misfit, elastic properties, deposition temperature, cation segregation and the space charge effects, are discussed.

“…It is now well-established that the manner in which molecular building blocks are arranged within supramolecular structures has a tremendous effect on their physical and chemical properties [5,6]. In comparison to organic supramolecular chemistry, the prediction of the solid-state structure of metal-containing crystals is more challenging due to the complexity of predicting the structural outcome of the supramolecular architecture [7][8][9]. In this regard, supramolecular chemists have attempted to understand the rules of supramolecular assembly of metalcontaining compounds by studying the solid-state structures of these systems using X-ray crystallography data to provide a detailed picture of the supramolecular structure [10,11].…”

Zn(II) and Cd(II) coordination compounds containing 4-((pyridin-4-ylmethylene)amino)phenol ligands were synthesized and then characterized using spectroscopic techniques and single crystal X-ray crystallography. The molecular structure and crystal packing of these complexes, as well as the packing of related compounds, were investigated using geometrical, Hirshfeld surface analyses, and theoretical calculations. The supramolecular architecture of these coordination complexes is governed by a combination of πꞏꞏꞏπ stacking, C-Hꞏꞏꞏπ, O-HꞏꞏꞏN, and C-HꞏꞏꞏX hydrogen bonding interactions. This study provides further insight into the understanding of the coordination chemistry of group IIB containing Schiff-base ligand and the role of weak non-covalent interactions in the solid-state structure of coordination compounds.
