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

ABSTRACT: The title imidazolium-based ionic-liquid salt, C(18)H(24)N(4) (2+)·2BF(4) (-), has the cation lying about a center of inversion. The five-membered imidazole ring is approximately perpendicular to the six-membered phenyl-ene ring [dihedral angle = 86.9?(1)°]. The tetra-fluoro-borate anion is disordered over two sites in a 0.722?(3):0.278?(3) ratio.
