چکیده
The title compound, C18H24N4, resides on a crystallographic inversion centre, so that the asymmetric unit comprises one half-mol-ecule. The piperazine ring adopts a chair conformation, with the mean planes of the two equatorial pyridine rings parallel to each other and separated by 2.54 (3) Å. No classical hydrogen bonds are observed.

In the title hydrated mol-ecular salt, C(6)H(16)N(2) (+)·2PF(6) (-)·2H(2)O, the complete 1,4-dimethyl-piperazine-1,4-diium dication is generated by crystallographic inversion symmetry and both C-N bonds are in equatorial orientations. In the crystal, the components are linked by O-H⋯F and N-H⋯O hydrogen bonds but there are no direct links between cations and anions.
