Only the third known example of a homoleptic polynitrogen species besides N 2 and N 3 − , the N 5 + ion possesses surprising stability and can be isolated on a macroscopic scale as its AsF 6 − salt. The assigment of the C 2v ‐symmetric structure (shown schematically) predicted by calculations was supported by IR and Raman as well as 14 N and 15 N NMR spectroscopic studies of the isotopically labeled product.
