33′-Di-n-propyl-11′-(13-phenyl­ene­dimethyl­ene)di(1H-imidazol-3-ium) bis­(hexa­fluorophosphate)

摘要

In the title compound, C20H28N4 ²⁺·2PF6 ⁻, the dihedral angles between the benzene ring and the imidazole rings are 70.18 (11) and 69.83 (11)°, while the imidazole rings form a dihedral angle of 40.52 (12)°. In the crystal, weak C—H⋯F inter­actions link the mol­ecules into a two-dimensional network parallel to (001). A π–π inter­action with a centroid–centroid distance of 3.601 (1) Å is also observed in the crystal structure.
