Halogenatome

Halogenatome is a hypothetical class of nanoscale materials posited in theoretical chemistry and materials science. The term describes a stable lattice unit designed to incorporate halogen atoms within a solid framework, allowing tunable halogen content and reversible uptake and release. The concept aims to enable programmable halogen chemistry without compromising structural integrity.

In proposed models, halogenatomes consist of a host matrix—often a covalently connected network or layered lattice—with halogen species occupying interstitial sites or substituting for host atoms, forming covalent or donor–acceptor interactions. The envisioned properties include adjustable electronic structure, potential energy storage capacity for halogen species, chemical reversibility, and resilience to cycling. The exact geometry and bonding vary across theoretical treatments, with some models emphasizing two-dimensional sheets and others three-dimensional frameworks.

Active experimental verification remains lacking. Halogenatome concepts arise from computational simulations and speculative proposals rather than demonstrated syntheses. Realization would require advanced solid-state synthesis techniques, high-pressure or plasma-assisted methods, and careful control of halogen incorporation to prevent phase separation or unwanted reactions. At present, there is no broadly accepted experimental evidence for a halogenatome material.

If validated, halogenatome materials could impact halogen storage and release technologies, catalysis through tunable halogen reactivity, and the design of responsive materials for energy or environmental applications. However, the concept remains debated within the scientific community, and the term halogenatome is not part of standard nomenclature.
