Abstract

In the title mol­ecular salt, C18H24N4 2+·2PF6 −, the complete dication is generated by a crystallographic inversion centre. The central benzene ring makes a dihedral angle of 77.19 (9)° with each of the imidazole rings. In the crystal, C—H⋯F inter­actions link the cations and anions into layers lying parallel to the bc plane. The hexa­fluoro­phosphate anion is disordered over two sets of sites in a 0.520 (11):0.480 (11) ratio.
