(a) A monoclinic unit cell of NO+NO3− at 37 GPa. (b) A representation of the trigonal planar nitrate (top) and linear nitro­sonium (bottom) ions with bond lengths and bond angles indicated. (c)–(d) The environment of the O2 and N2 atoms forming the NO+ cation: both N2 and O2 atoms are fivefold coordinated by negatively charged oxygen atoms from the NO3− anions. The lengths are provided in Å.
