(a) Pressure dependence of the unit-cell volume per formula unit of nitrosonium nitrate. The volume of a 2:1 N₂–O₂ mixture (Olijnyk, 1990

; Akahama et al., 1995

; Gregoryanz et al., 2007

) is significantly larger than that of NO⁺NO₃⁻ at corresponding pressures. The volume determined by Meng et al. (2006

) (red dot) fits well the equation of state of nitrosonium nitrate obtained in the current work. The data represented by the blue triangles were obtained by DFT calculations. (b) The lattice parameters of NO⁺NO₃⁻ as a function of pressure.
