title: 2,7-Dimethyl-2,7-diazo-niapyrene bis-(hexa-fluoro-phosphate).
abstract: In the title compound, C(16)H(14)N(2) (2+)·2PF(6) (-), the 2,7-dimethyl-2,7-diaza-pyrenium (DM-diaz) cation lies on a crystallographic twofold rotation axes. The diaz groups are nearly coplanar, with a maximum deviation of 0.008 (3) Å. In the crystal, mol-ecules are linked into a two-dimensional lamellar framework parallel to (104) through weak C-H⋯F inter-actions.
