A 2025 study in Chemical Science found that changing the three-dimensional arrangement of energetic groups on a cage-like molecule can alter its density, stability and measured detonation performance—even when the isomers have the same molecular formula. The work is laboratory evidence that stereochemistry matters in this class of materials, not proof that the compounds are commercially available or broadly equivalent to an established explosive.
What the researchers changed
Stereoisomers share the same atom-to-atom connectivity but differ in how atoms are arranged in space. Huan Li and colleagues tested whether that distinction affects energetic materials built on a 2,4,10-trioxaadamantane cage. They synthesized four trinitrate diastereomers and three tetranitro diastereomers, then examined how their configurations related to material properties. The paper appeared in Chemical Science in 2025. Read the primary article.
The study addresses a potential blind spot in property prediction: methods that model molecules in the gas phase may not account for stereochemistry or the crystal packing found in a solid. In a Chemistry World report published 2 September 2025, researcher Jun Luo said the team wanted to synthesize and test three-dimensional compounds because they could be more affected by stereochemistry than many flatter molecules.

What differed among the isomers
Members of each series share a molecular formula and the positions of their energetic groups, but the paper reports differences in density, stability and detonation performance. The arrangement of groups can influence how molecules pack in a crystal, providing a structural explanation for differences in density. The study does not establish a complete, decision-ready safety or performance ranking across all seven compounds.

The densest reported isomer
The (exo,endo) tetranitro diastereomer had the highest crystal density in the seven-compound set: 1.980 g cm−3, as reported by the research team in 2025. The authors attributed its high density to strong intermolecular hydrogen bonding. This is a measurement for that compound in this study, not a general density figure for cage-like energetic materials.
Oxygen balance is not a performance verdict
The primary paper reports positive oxygen-balance values based on CO for all seven compounds. That is a paper-specific calculated or material descriptor; it should not be read as independent proof of practical explosive performance.

What the detonation test showed—and did not show
In a lead-plate perforation test, the high-density tetranitro isomer performed comparably to RDX. Chemistry World reports that the researchers also tested the lowest-density diastereomer in this comparison. The RDX result applies to this particular test only: it does not establish equivalence across other performance measures, conditions or applications.
The paper’s findings are therefore best understood as a demonstration that stereochemical configuration can influence properties and a result in one specific test. They do not show that the compounds are suitable for general use, commercially available or interchangeable with established explosives.

Why the result matters to materials research
The work suggests that researchers may be able to change a solid energetic material’s properties by adjusting the relative spatial arrangement of its functional groups, rather than changing the molecule’s connectivity. That makes stereochemistry and crystal packing relevant considerations when designing or evaluating three-dimensional energetic compounds.
In the same Chemistry World report, high-energy-density-materials expert Dheeraj Kumar said the work could encourage chemists to revisit existing molecules and consider whether changing the relative positions of their explosophores alters energetic and physical properties. That is a research implication, not evidence that a particular redesign will improve performance or safety.

Safety and access
The primary paper warns that some compounds are potentially explosive and sensitive to impact and friction. It explicitly says mechanical actions such as scraping or scratching must be avoided and calls for appropriate standard safety precautions for work involving these substances. The study is not a basis for attempting to prepare, handle or use them outside properly equipped and qualified research settings.
