N5+: A Novel Homoleptic Polynitrogen Ion as a High Energy Density Material

Abstract

The assignment of the 15N NMR signals of N5+ in the Communication by K. O. Christe et al. in Issue 13/14, 1999, pp. 2004–2010 were inadvertently reversed. The signal at δ=−237.3 (calculated: −235) corresponds to the central N atom N3, and that at δ=−100.4 (calculated: −95) to N1 (see for example Table 1 in this contribution).
