Only the third known example of a homoleptic polynitrogen species besides N and N , the N ion possesses surprising stability and can be isolated on a macroscopic scale as its AsF salt. The assigment of the C-symmetric structure (shown schematically) predicted by calculations was supported by IR and Raman as well as N and N NMR spectroscopic studies of the isotopically labeled product.
作为除N₂和N₃⁺之外第三种已知的同配多氮物种，N₅⁺离子具有惊人的稳定性，并且可以作为其AsF₆盐在宏观尺度上分离出来。计算预测的C对称结构（示意图所示）通过红外光谱、拉曼光谱以及对同位素标记产物的¹⁵N和¹⁴N核磁共振光谱研究得到了证实。
