Hexazine

Hexazine, also known as cyclononazine or azacyclononane, is a hypothetical chemical compound with the molecular formula C0N6. It is a cyclic molecule consisting of nine atoms arranged in a ring, where all atoms are nitrogen. The theoretical structure proposes a highly strained, nearly planar ring system.

The concept of hexazine has primarily emerged from theoretical chemistry calculations. These studies suggest that due to the inherent repulsion between the lone pairs of electrons on adjacent nitrogen atoms and significant ring strain, hexazine would be an extremely unstable and highly energetic compound. It is predicted to decompose rapidly, likely explosively, upon formation.

Due to its predicted instability, hexazine has not been experimentally synthesized or isolated. Its existence remains speculative and is of interest in theoretical studies exploring the limits of nitrogen-based ring structures and high-energy materials. Research into such compounds contributes to understanding chemical bonding and the potential for novel energetic molecules, even if they are not practically achievable. The high nitrogen content suggests potential applications in energetic materials if stability issues could somehow be overcome, though this remains firmly in the realm of theoretical exploration.
