RESUMO
In the crystal structure of the title compound, C(16)H(19)N(4)O(2) (+)·PF(6) (-), the cations and anions are situated on centres of inversion. Thus, the N-H H atom is disordered over both N atoms due to symmetry. In the crystal, mol-ecules are connected via N-Hâ¯F and N-Hâ¯O hydrogen bonds. The cation adopts the â¯AAA⯠trans conformation in the solid state.
