title: 3-(9-Anthrylmethyl)-1-benzylperimi-dinium hexa-fluoro-phosphate.
abstract: In the title compound, C(33)H(25)N(2) (+)·PF(6) (-), the naphthalene ring system is twisted with respect to the anthracene and benzene rings, making dihedral angles of 72.40 (3) and 71.39 (4)°, respectively. The crystal structure is stabilized by intermolecular C-H⋯F hydrogen bonding. Four F atoms of the hexa-fluoro-phosphate anion are disordered over two sets of sites in a 0.645 (4):0.355 (4) ratio.
