A new isomerism strategy transforms non-framework ionic materials into robust frameworks, enhancing energy and stability. This breakthrough offers a novel pathway for designing advanced ionic framework materials with superior properties.
Area of Science:
- Materials Science
- Chemistry
- Crystallography
Background:
- Ionic framework materials are crucial in chemistry and materials science.
- Current synthesis methods often involve trial-and-error, limiting efficient development.
- A need exists for predictable strategies to construct ionic frameworks.
Purpose of the Study:
- To introduce a novel isomerism strategy for synthesizing ionic framework materials.
- To enable structural transformation from non-framework to framework architectures.
- To investigate the structure-property relationships in newly developed ionic frameworks.
Main Methods:
- Isomerism strategy for structural transformation.
- Synthesis of novel ionic frameworks (F-NH3NH2, F-NH3OH).
- Characterization using single-crystal X-ray diffraction.
- Quantum chemical calculations for property analysis.
Main Results:
- Developed ionic frameworks (F-NH3NH2, F-NH3OH) show enhanced energy and stability over non-framework isomers.
- F-NH3OH exhibits exceptional detonation performance (9442 m/s, 38.4 GPa) and mechanical sensitivity (120 N friction, 7 J impact).
- Performance is attributed to reinforced hydrogen-bonding networks from complete structural coverage.
Conclusions:
- The isomerism strategy provides a robust method for constructing ionic framework materials.
- Isomerization significantly influences the structure and properties of ionic systems.
- This work advances the design principles for high-performance energetic materials.

02:46Crystal Field Theory - Tetrahedral and Square Planar Complexes
Crystal field theory (CFT) is applicable to molecules in geometries other than octahedral. In octahedral complexes, the lobes of the dx2−y2 and dz2 orbitals point directly at the ligands. For tetrahedral complexes, the d orbitals remain in place, but with only four ligands located between the axes. None of the orbitals points directly at the tetrahedral ligands. However, the dx2−y2 and dz2 orbitals (along the Cartesian axes) overlap with the ligands less than the dxy,...

Conjugated systems containing an even number of π-electron pairs undergo a conrotatory ring closure. For example, thermal electrocyclization of (2E,4E)-2,4-hexadiene, a conjugated diene containing two π-electron pairs, gives trans-3,4-dimethylcyclobutene.
02:34Structural Isomerism
Isomers are different chemical species that have the same chemical formula. Structural isomerism of coordination compounds can be divided into two subcategories, the linkage isomers and coordination-sphere isomers.
Linkage isomers occur when the coordination compound contains a ligand that can bind to the transition metal center through two different atoms. For example, the CN− ligand can bind through the carbon atom or through the nitrogen atom. Similarly, SCN− can...
02:52Stereoisomerism
Isomers are different chemical species that have the same chemical formula.
Transition metal complexes often exist as geometric isomers, in which the same atoms are connected through the same types of bonds but with differences in their orientation in space. Coordination complexes with two different ligands in the cis and trans positions from a ligand of interest form isomers. For example, the octahedral [Co(NH3)4Cl2]+ ion has two isomers (Figure 1) In the cis...
