Nitrosyl and dioxygenyl cations and their salts—Similar but further investigation needed

The O2+ ion is sufficiently similar in size to NO+ and so the difference in lattice energy in salts with a common anion can be expected to be negligible. Comparative analysis of O2F vs. NOF and of O2+ vs. NO+-salts is given in this paper and some surprising and unexpected differences between corresponding species are discussed.
