Preparation of a neutral nitrogen allotrope hexanitrogen <i>C</i><sub>2h</sub>-N<sub>6&#xa0;</sub>

Nature, Published online: 11 June 2025; doi:10.1038/s41586-025-09032-9The facile synthesis and spectroscopic identification of previously unreported hexanitrogen C2h-N6 is described, representing experimentally realized neutral molecular nitrogen allotropes beyond N2 that exhibit unexpected stability.
