1,1',2,2'-Tetra-methyl-3,3'-(p-phenyl-enedimethyl-ene)diimidazol-1-ium bis-(hexa-fluoridophosphate).

ABSTRACT: The title imidazolium-based ionic-liquid salt, C(18)H(24)N(4) (2+)·2PF(6) (-), has the cation lying about a center of inversion. The five-membered imidazole ring is disordered over two positions (the methyl substituents are ordered). This imidazole ring is approximately perpendicular to the six-membered phenyl-ene ring [dihedral angle = 81.3?(8)° for one disorder component and 83.8?(8)° for the other; the two components are off-set by 2.7?(8)°]. The crystal is a non-merohedral twin with a twin component of 23%.

3,3'-Dimethyl-1,1'-[2,2'-bipyridine-5,5'-diylbis(methyl-ene)]diimidazol-3-ium bis-(hexa-fluoro-phosphate).

Project description:The title compound, C(20)H(22)N(6) (2+)·2PF(6) (-), was prepared by the reaction of 5,5'-bis-(bromo-meth-yl)-2,2'-bipyridine with 1-methyl-imidazole. The main mol-ecule lies on an inversion center located at the mid-point of the C-C bond joining the two pyridine rings. The asymmetric unit therefore contains one half-mol-ecule and one hexa-fluoro-phosphate anion. The dihedral angle between the pyridine and imidazole rings is 76.93 (7)°. In the crystal, weak inter-molecular C-H⋯F hydrogen bonds contribute to the stabilization of the packing.
