Summary
The study explored eleven nitrogen cluster isomers (N13+ and N13-), identifying the most stable structures using advanced computational methods. The most stable N13- isomer shows potential for experimental observation as a short-lived species.
Area of Science:
- Computational Chemistry
- Theoretical Chemistry
- Materials Science
Background:
- Nitrogen clusters are of interest due to their potential energetic properties.
- Understanding the stability and reactivity of nitrogen clusters is crucial for their synthesis and application.
Purpose of the Study:
- To investigate the structures and stabilities of eleven N13+ and N13- isomers.
- To determine the most stable configurations and their potential for experimental observation.
Main Methods:
- Second-order Moller-Plesset (MP2) and density functional theory (DFT) methods were employed.
- Calculations were performed using the B3LYP/(aug)-cc-pVDZ level for decomposition pathway analysis.
Main Results:
- Five N13+ and six N13- isomers were identified as local minima.
- The most stable N13+ cation (C-2) features a pentazole ring and N4 chains, similar to N11+.
- The most stable N13- structure (A-2) consists of a pentazole and a six-membered ring, differing from N7-, N9-, and N11- clusters.
Conclusions:
- Structure C-2 is predicted to be difficult to observe experimentally.
- Structure A-2 is suggested to be observable as a short-lived species.
- The distinct structures of N13+ and N13- isomers highlight unique chemical properties of larger nitrogen clusters.
