Abstract
The title compound, C(13)H(22)N(4)O(2) (2+)·2PF(6) (-), was prepared by the anion exchange of the dibromide ionic liquid with potassium hexa-fluoro-phosphate. The two imidazole rings are each planar (r.m.s. deviations = 0.0016 and 0.0060 Å) and make a dihedral angle of 45.3 (18)°. Intra-molecular O-H⋯F hydrogen bonds occur. Inter-molecular C-H⋯F, O-H⋯O and C-H⋯O hydrogen bonds stabilize the crystal structure.
摘要
标题化合物C(13)H(22)N(4)O(2)(2+)·2PF(6)(-)是通过二溴离子液体与六氟磷酸钾进行阴离子交换制备的。两个咪唑环均为平面结构（均方根偏差分别为0.0016和0.0060 Å），且二面角为45.3(18)°。分子内存在O-H⋯F氢键。分子间的C-H⋯F、O-H⋯O和C-H⋯O氢键稳定了晶体结构。
