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.
摘要
标题为咪唑基离子液体盐C(18)H(24)N(4)(2+)·2BF(4)(-)，其阳离子位于一个反演中心周围。五元咪唑环与六元苯环大致垂直[二面角 = 86.9 (1)°]。四氟硼酸根阴离子在两个位置上无序排列，比例为0.722 (3):0.278 (3)。
