In the mononuclear complex title salt, all of the non-H atoms of the cation lie on a mirror plane, as do the N and one O atom of the nitrate anion, such that the planes of the cation and anion are mutually orthogonal. In the crystal, layers parallel to (010) are generated by N—HO hydrogen bonds, supported by short SO [3.196 (4) and 3.038 (3) Å] and SS contacts [3.4392 (13) Å].
