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

Abstract

In the title compound, C20H28N42+·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.
