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 hydr

The hydrogensulfate anions of the title compound, C 19 H 18 N 3 + ÁHSO 4 À , form centrosymmetric hydrogen-bonded dimers. In the cation, the dihedral angles between the phenyl rings and the plane defined by the central guanidinium fragment are in the range 41.46 (6)-67.11 (5) .
In the title crystal structure, C~19~H~36~N~3~ ^+^·Cl^−^, the central C atom of the __N__,__N__′,__N__′′-tricyclohexylguanidinium ion and the chloride ion both lie on positions of site symmetry 3. Weak N—H...Cl hydrogen bonds [N...Cl = 3.539 (3) Å] link anions and cations, forming a three-dimensiona
