✦ Synopsis

The title salt, C~19~H~18~N~3~
^+^·NO~3~
^−^, has two symmetry-independent cations and two symmetry-independent anions in the asymmetric unit, with almost identical geometries. Bond lengths and angles within the guanidinium unit are close to those expected for a C__sp__
^2^ atom. Intermolecular hydrogen bonds link anions and cations, forming chains that run along the c axis.
