3,3'-Dicyclo-pentyl-1,1'-(1,3-phenyl-enedimethyl-ene)dibenzimidazol-1-ium bis-(hexa-fluoro-phosphate).
In the title compound, C(32)H(36)N(4) (2+)·2PF(6) (-), the cation and the anions each have crystallographic twofold rotation symmetry. The benzimidazole ring is almost planar [r.m.s. deviation = 0.0161 (1) Å] and makes a dihedral angle of 5.77 (4)° with its symmetry-related component and a dihedral angle of 80.96 (5)° with the central benzene ring. The cyclo-pentyl ring adopts a half-chair conformation. In the crystal, mol-ecules are linked into a three-dimensional network through C-H⋯F hydrogen bonds. A C-H⋯π inter-action is also observed.
